Sequence Check Order
Differences, then ratios, then special series.
Arithmetic vs Geometric
Arithmetic
- Adds constant
- Linear growth
- Constant differences
Geometric
- Multiplies constant
- Exponential growth
- Constant ratios
Add vs multiply
Which Pattern to Try
- Numbers keep growing fast→Test ratios first(Geometric or exponential)
- Differences look constant→Confirm arithmetic sequence
- Differences keep growing→Check second-order pattern
- Every term sums prior two→Try Fibonacci-style rule
- Alternating jumps appear→Split odd even positions
- Values shrink toward zero→Test halving pattern
Sequence Patterns
- Arithmetic
- Add same constant
- Geometric
- Multiply same ratio
- Fibonacci
- Sum prior two terms
- Primes
- Only divisible by itself
- Perfect squares
- n squared pattern
- Perfect cubes
- n cubed pattern
- Triangular numbers
- Differences increase by one
- Factorial
- Multiply by next integer
- Second-order series
- Differences increase steadily
- Interleaved series
- Two hidden alternating sequences
- Powers of two
- Double or halve term
- Combo pattern
- Multiply then add step
Sequence Solving Strategy
- Differences first
- Check constant or growing gaps
- Ratios next
- Check for multiplication pattern
- Try special series
- Squares cubes primes factorials
- Split positions
- Odd and even hide sequences
- Alternating operations
- Pattern may swap functions
- Verify twice
- Test rule on two terms
Time Banking Strategy
Bank seconds on easy items for the hard ones.
Rate vs Ratio Problems
Rate
- Per unit time
- Add to combine
- Work or speed
Ratio
- Compares two quantities
- Cross multiply to solve
- Proportion problems
Time-based vs quantity-based
Which Math Setup to Use
- Sees percent markup word→Base is wholesale not retail
- Two rates work together→Add rates, not times
- Ratio given with total→Set up cross proportion
- Two percent changes stack→Multiply factors sequentially
- Objects move toward each other→Add the closing speeds
- Overlap between two groups→Subtract double-counted overlap
Word Problem Types
- Markup
- Retail equals wholesale plus markup
- Ratio proportion
- Cross multiply to solve
- Combined rate
- Add individual work rates
- Weighted average
- Sum each times its weight
- Mixture
- Concentration times volume added
- Closing speed
- Add both travel speeds
- Gear ratio
- Inverse of tooth count
- Compound percent
- Multiply factors, never add
- Work formula
- Workers times days constant
- Overlap sets
- Add then subtract overlap
Arithmetic Shortcuts
- No calculator
- Master fast mental math
- Percent of
- Multiply by decimal form
- Percent change
- Always use original base
- Two-step percent
- Never simply add percentages
- Distance formula
- Rate multiplied by time
- Average removal
- Total minus remaining sum
- Break-even swing
- Loss needs bigger gain
Bridge the Analogy
Build one sentence bridge, then match it exactly.
Word vs Figure Analogies
Word analogy
- Relationship between meanings
- Synonym or function link
- Vocabulary knowledge helps
Figure analogy
- Relationship between shapes
- Rotation or fill link
- No vocabulary needed
Meaning link vs visual link
Analogy Relationship Types
- Synonym pair
- Same core meaning
- Antonym pair
- Opposite core meaning
- Part to whole
- Piece belongs to whole
- Tool to user
- Instrument serves professional
- Cause to effect
- First triggers second
- Degree pair
- Weak scales to strong
- Function pair
- Shared purpose or use
- Category pair
- Member belongs to class
Verbal Deduction Cues
- Despite signals
- Unexpected contrast follows
- Because signals
- Direct cause given
- However signals
- Reversal of direction
- Best supported
- Only what is stated
- Overreach trap
- Avoid absolute wording
- Not stated
- Eliminate outside assumptions
- Inference
- Evidence combined with logic
Stack the Figure Rules
Sides, fills, and lines can all change together.
Rotation vs Reflection
Rotation
- Turns around point
- Keeps handedness
- Angle changes
Reflection
- Mirrors across axis
- Flips handedness
- Left-right reversed
Turn vs mirror
Spatial Transformations
- Rotation
- Turns around a point
- Reflection
- Mirrors left and right
- Translation
- Slides without changing shape
- Dilation
- Changes size only
- Net folding
- Flat pattern becomes solid
- Cube net
- Six squares fold closed
- Cross net
- Classic shape folds cube
Figure Pattern Rules
- Side progression
- Each step adds one side
- Fill rotation
- Pattern cycles through rows
- Dual rule
- Row and column combine
- Matrix constraint
- No repeat within row
- Doubling lines
- Internal lines double each step
- View check
- Sphere shows circle everywhere
- Odd one out
- Find the missing trait
Only Contrapositive Is Equal
Converse and inverse lie; contrapositive tells truth.
Contrapositive vs Converse
Contrapositive
- Not Q then not P
- Always equivalent
- Safe to use
Converse
- Q then P
- Not equivalent
- Common trap
Flip and negate only
Which Logic Rule Applies
- If-then with antecedent true→Apply modus ponens
- If-then with consequent false→Apply modus tollens
- Need an equivalent statement→Form the contrapositive
- Either-or, but not both→Treat it as XOR
- All-some syllogism chain→Draw nested circles
- Three plus variables given→Build a truth table
Conditional Logic Rules
- Modus ponens
- P true makes Q true
- Modus tollens
- Not Q makes not P
- Contrapositive
- Always logically equivalent
- Converse
- Not logically equivalent
- Inverse
- Not logically equivalent
- Chain rule
- A leads on to C
- XOR statement
- Exactly one side true
Some vs All Quantifiers
Some
- At least one
- Leaves rest unknown
- Weaker claim
All
- Every single case
- Full subset relation
- Stronger claim
Partial vs total
Syllogism and Truth Rules
- All A are B
- A is a subset
- Some means
- At least one case
- No valid conclusion
- Overlap stays unknown
- Undistributed middle
- Common syllogism fallacy
- Truth rows
- 2 raised to n
- AND rule
- Both sides must hold
- OR rule
- One side must hold
- NOT rule
- Flips true and false
Common Traps
Converse vs Contrapositive
Converse not equivalent ≠ Contrapositive always equivalent
Combined Rates vs Combined Times
Add the rates ≠ Never average the times
Sequential Percents vs Simple Sum
Multiply the factors ≠ Do not add percentages
Some vs All in Syllogisms
Some means not every case ≠ All means full subset
Wholesale Base vs Retail Base
Markup uses wholesale ≠ Not the retail price
Rotation vs Reflection Symmetry
Rotation keeps handedness ≠ Reflection flips handedness
Fixed Pace vs Time Banking
45 sec average only ≠ Bank time on easy ones
