series, jump

Question 2

Find the next term: T1, A8, H15, O22
Letters move by +7, number increments by 7. Wraparound used for letters.
series, modular

Question 3

What comes next in the series: C3, E6, H12, L24
Letters advance by increasing steps: 1, 2, 3, 4; numbers double each time.
series, jump

Question 4

Find the next term: I, 5, L, 8, O, ?
Odd terms: letters +3; Even terms: numbers +3.
series, alternate

Question 5

What is the next term in the sequence: H5, J8, L1, N4, P7?
Letters advance by 2 (starting H), digits advance by 3 (mod 10).
multi_skip, double_encode

Question 6

In sequence: A7, C6, E5, G4, I3, K2, M1, what is the term 2 positions before the 5th term?
Reference required position backward.
reverse, crossref, series

Question 7

Find the next term if odd position letters advance by 3, even position numbers follow (i+2)*2: K4, P4, Q8, V8, W12
Odd-indexed positions: letter advances by 3 from K, number = (position+2)×2 = 14 at position 5. Next term: Z14.
embed_logic, series

Question 8

Find the next palindromic term in the pattern: KLK, LML, MNM, NON
Each term is a 3-letter palindrome, with both outer and middle letters moving forward by 1 each time.
series, palindrome

Question 9

Find the next palindromic term in the pattern: FGF, GHG, HIH, IJI
Each term is a 3-letter palindrome, with both outer and middle letters moving forward by 1 each time.
series, palindrome

Question 10

Find the next term in the series: T1, U2, V3, W5
Pattern: Letter increases by 1 each position. Numbers follow the pattern: 1, 2, 3, 5, 8... (each number after the first two is the sum of the two preceding numbers).
Next: Letter = X, Number = 8 → X8
series, position

Question 11

What comes next in the hybrid series: G10, K20, S40, I80
Letters move by steps: 2, 4, 8, 16, numbers double each time. Next step +32 for letter, ×2 for number.
series, hybrid

Question 12

Find the missing term in the series: H2, J3, L4, ?, P6
Each step adds 2 to letter and 1 to number.
The missing term comes fourth: N5.
series, missing term

Question 13

Find the next term in the series: D1, E2, F3, G5
Pattern: Letter increases by 1 each position. Numbers follow the pattern: 1, 2, 3, 5, 8... (each number after the first two is the sum of the two preceding numbers).
Next: Letter = H, Number = 8 → H8
series, position

Question 14

Find the next term in the series: A0!, C3@, E6#, G9$, I2%
Letters advance by +2 (mod 26), digits advance by +3 (mod 10), symbols cycle through ['!', '@', '#', '$', '%']. Next term: letter=K, digit=5, symbol=^ → K5^.
symbol, group, series

Question 15

Find the next term: S1, T4, U9, V16
Number is term position squared (1,4,9,16,25). Letter increases by one each time.
series, math transform

Question 16

Find the next term in the series: A0!, C3@, E6#, G9$, I2%
Letters advance by +2 (mod 26), digits advance by +3 (mod 10), symbols cycle through ['!', '@', '#', '$', '%']. Next term: letter=K, digit=5, symbol=^ → K5^.
symbol, group, series

Question 17

What comes next: F1, I4, L7, O10 ?
Letters move +3, numbers +3. Continue pattern: next is R13.
series, pattern

Question 18

This series alternates letters and numbers, each increasing by 3.
Last term: S10 → next: V13.
series, next term

Question 19

In the sequence: N0#, O1$, P2*, Q3!, R4@, S5#, T6$, which term is three places after the term with digit '2'?
Locate digit 2 in the sequence (position 3), then jump 3 places forward to position 6: S5#.
relative, position, series
