Worksheet 19 of 30 (63% complete)

Question 1

What comes next in the series: E1, G2, K4, S8

Letters advance by increasing steps: 1, 2, 4, 8; numbers double each time.

series, jump

Question 2

In the sequence: M4!, N5@, O6#, P7$, Q8*, R9!, S0@, 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: Q8*.

relative, position, series

Question 3

Find the next term: K1, R8, Y15, F22

Letters move by +7, number increments by 7. Wraparound used for letters.

series, modular

Question 4

Find the term that does NOT follow the series: A2, D5, I8, J11, M14

The series follows +3 for both letter and number. Position 3: should be G, but given term is I (I8).

series, find wrong

Question 5

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 6

Find the missing term in the series: C2, E3, G4, ?, K6

Each step adds 2 to letter and 1 to number.
The missing term comes fourth: I5.

series, missing term

Question 7

Find the missing term in the series: G2, J4, M6, ?, S10

Each step adds 3 to letter and 2 to number.
The missing term comes fourth: P8.

series, missing term

Question 8

What comes next: H1, K4, N7, Q10 ?

Letters move +3, numbers +3. Continue pattern: next is T13.

series, pattern

Question 9

Find the next group in the series: KL1415, NO1718, QR2021

Groups: Each is 2 letters and 2 digits, increasing by 3 each time. Next is TU2324.

series, grouped

Question 10

Find the next palindromic term in the pattern: LML, MNM, NON, OPO

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

series, palindrome

Question 11

Find the next term if odd position letters advance by 3, even position numbers follow (i+2)*2: H4, M4, N8, S8, T12

Odd-indexed positions: letter advances by 3 from H, number = (position+2)×2 = 14 at position 5. Next term: W14.

Question 12

Find the next term in the series: M3, N6, O9, P36

Pattern: Letter increases by 1 each position. Numbers follow: start 2, then +1=3, ×2=6, +3=9, ×4=36, +5=41...
Next: Letter = Q, Applying +5 to 36 = 41 → Q41

series, position

Question 13

What comes next: G1, J4, M7, P10 ?

Letters move +3, numbers +3. Continue pattern: next is S13.

series, pattern

Question 14

Find the next term if odd position letters advance by 3, even position numbers follow (i+2)*2: A4, F4, G8, L8, M12

Odd-indexed positions: letter advances by 3 from A, number = (position+2)×2 = 14 at position 5. Next term: P14.

Question 15

What comes next in the hybrid series: H4, K8, M16, N32

Letters move by steps: 4, 3, 2, 1, numbers double each time. Next step +0 for letter, ×2 for number.

series, hybrid

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

In the sequence: A2*, B3!, C4@, D5#, E6$, F7*, G8!, which term is three places after the term with digit '2'?

Locate digit 2 in the sequence (position 1), then jump 3 places forward to position 4: D5#.

relative, position, series

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
