Worksheet 2 of 30 (6% complete)

Question 1

In sequence: A7, C6, E5, G4, I3, K2, M1, what is the term 2 positions before the 6th term?

Reference required position backward.

reverse, crossref, series

Question 2

Find the next palindromic term in the pattern: RSR, STS, TUT, UVU

Each term is a 3-letter palindrome, with both outer and middle letters moving forward by 1 each time.

series, palindrome

Question 3

In the sequence: D3#, E4$, F5*, G6!, H7@, I8#, J9$, 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: H7@.

relative, position, series

Question 4

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 5

Find the missing term in the series: E2, G4, I6, ?, M10

Each step adds 2 to letter and 2 to number.
The missing term comes fourth: K8.

series, missing term

Question 6

Find the next term in the series: R3, T6, V9, X12

Pattern: Letter advances by 2 positions each time, Number increases by 3 each time.
Next: Letter = Z, Number = 15 → Z15

series, position

Question 7

Find the next group in the series: LM1314, NO1516, PQ1718

Groups: Each is 2 letters and 2 digits, increasing by 2 each time. Next is RS1920.

series, grouped

Question 8

Find the next term in the series: K1, N4, Q7, T10

This series alternates letters and numbers, each increasing by 3.
Last term: T10 → next: W13.

series, next 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

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 11

Find the next term: D, 4, F, 6, H, ?

Odd terms: letters +2; Even terms: numbers +2.

series, alternate

Question 12

Find the next term if odd position letters advance by 3, even position numbers follow (i+2)*2: M4, R4, S8, X8, Y12

Odd-indexed positions: letter advances by 3 from M, number = (position+2)×2 = 14 at position 5. Next term: B14.

embed_logic, series

Question 13

In sequence: A7, C6, E5, G4, I3, K2, M1, what is the term 2 positions before the 4th term?

Reference required position backward.

reverse, crossref, series

Question 14

Find the next term: N1, Q4, T7, W10

Letters move by +3, number increments by 3. Wraparound used for letters.

series, modular

Question 15

What comes next in the series: B2, C4, E8, G16

Letters advance by increasing steps: 1, 1, 2, 2; numbers double each time.

series, jump

Question 16

Find the missing term in the series: K2, N3, Q4, ?, W6

Each step adds 3 to letter and 1 to number.
The missing term comes fourth: T5.

series, missing term

Question 17

What comes next in the series: D1, E2, G4, J8

Letters advance by increasing steps: 1, 1, 2, 3; numbers double each time.

series, jump

Question 18

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 19

Find the next term in the series: C1, D4, E9, F16

Pattern: Letter increases by 1 each position, Number is the square of the position number.
Position 1: C1
Position 2: D4
Position 3: E9
Position 4: F16
Position 5: Letter = G, Number = 5² = 25 → G25

series, position

Question 20
