Question 1

Find the next term: C, 3, E, 5, G, ?
Odd terms: letters +2; Even terms: numbers +2.
series, alternate

Question 2

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 3

In the sequence: C0!, D1@, E2#, F3$, G4*, H5!, I6@, 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: H5!.
relative, position, series

Question 4

Find the next term: I1, O7, U13, A19
Letters move by +6, number increments by 6. Wraparound used for letters.
series, modular

Question 5

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 6

What comes next in the series: E3, H6, M12, T24
Letters advance by increasing steps: 1, 3, 5, 7; numbers double each time.
series, jump

Question 7

In the sequence: A4!, B5@, C6#, D7$, E8*, F9!, G0@, which term is three places after the term with digit '2'?
Locate digit 2 in the sequence (position 2), then jump 3 places forward to position 5: E8*.
relative, position, series

Question 8

Find the missing term in the series: A2, D4, G6, ?, M10
Each step adds 3 to letter and 2 to number.
The missing term comes fourth: J8.
series, missing term

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 term: I1, J4, K9, L16
Number is term position squared (1,4,9,16,25). Letter increases by one each time.
series, math transform

Question 11

Fill in the missing term: Z11, X9, V7, ?, R3
Letters move back by 2; numbers -2 each time.
series, reverse

Question 12

Find the next term: N1, O4, P9, Q16
Number is term position squared (1,4,9,16,25). Letter increases by one each time.
series, math transform

Question 13

Find the next term if odd position letters advance by 3, even position numbers follow (i+2)*2: E4, J4, K8, P8, Q12
Odd-indexed positions: letter advances by 3 from E, number = (position+2)×2 = 14 at position 5. Next term: T14.
embed_logic, series

Question 14

What is the next term in the sequence: H2, J5, L8, N1, P4?
Letters advance by 2 (starting H), digits advance by 3 (mod 10).
multi_skip, double_encode

Question 15

Find the next term in the series: F3, G6, H9, I36
Pattern: Letter increases by 1 each position. Numbers follow: start 2, then +1=3, ×2=6, +3=9, ×4=36, +5=41...
Next: Letter = J, Applying +5 to 36 = 41 → J41
series, position

symbol, group, series

Question 18

Find the next group in the series: ST1617, UV1819, XY2021
Groups: Letter steps follow Fibonacci (1,2,3,5), numbers increase by 2 each time. Next is CD2223.
series, grouped

Question 19

In the sequence: P3*, Q4!, R5@, S6#, T7$, U8*, V9!, which term is three places after the term with digit '2'?
