Question 1

Find the next term: R1, X7, D13, J19
Letters move by +6, number increments by 6. Wraparound used for letters.
series, modular

Question 2

What comes next in the hybrid series: F10, H20, K40, P80
Letters move by steps: 1, 2, 3, 5, numbers double each time. Next step +8 for letter, ×2 for number.
series, hybrid

Question 3

Find the missing term in the series: D2, G3, J4, ?, P6
Each step adds 3 to letter and 1 to number.
The missing term comes fourth: M5.
series, missing term

Question 4

What is the next term in the sequence: C1, E4, G7, I0, K3?
Letters advance by 2 (starting C), digits advance by 3 (mod 10).
multi_skip, double_encode

Question 5

Find the next term in the series: F1, G2, H3, I5
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 = J, Number = 8 → J8
series, position

Question 6

What comes next in the hybrid series: B4, E8, L16, A32
Letters move by steps: 1, 3, 7, 15, numbers double each time. Next step +31 for letter, ×2 for number.
series, hybrid

Question 7

What comes next in the hybrid series: G4, M8, V16, H32
Letters move by steps: 3, 6, 9, 12, numbers double each time. Next step +15 for letter, ×2 for number.
series, hybrid

Question 8

In sequence: A7, C6, E5, G4, I3, K2, M1, what is the term 2 positions before the 3th term?
Reference required position backward.
reverse, crossref, series

Question 9

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 10

Find the next group in the series: NO1819, PQ2021, RS2223
Groups: Each is 2 letters and 2 digits, increasing by 2 each time. Next is TU2425.
series, grouped

Question 11

What is the next term in the sequence: D6, F9, H2, J5, L8?
Letters advance by 2 (starting D), digits advance by 3 (mod 10).
multi_skip, double_encode

Question 12

Find the next term: O, 10, Q, 12, S, ?
Odd terms: letters +2; Even terms: numbers +2.
series, alternate

Question 13

Find the next term: P1, Q4, R9, S16
Number is term position squared (1,4,9,16,25). Letter increases by one each time.
series, math transform

Question 14

Find the next term if odd position letters advance by 3, even position numbers follow (i+2)*2: N4, S4, T8, Y8, Z12
Odd-indexed positions: letter advances by 3 from N, number = (position+2)×2 = 14 at position 5. Next term: C14.
embed_logic, series

Question 15

Find the term that does NOT follow the series: C2, E4, G6, I8, M10
The series follows +2 for both letter and number. Position 5: should be K, but given term is M (M10).
series, find wrong
