Worksheet 30 of 30 (100% complete)

Question 1

Find the next term in the series: L1, N3, P5, R7

This series alternates letters and numbers, each increasing by 2.
Last term: R7 → next: T9.

series, next term

Question 2

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 3

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 4

Find the next term: G1, K5, O9, S13

Letters move by +4, number increments by 4. Wraparound used for letters.

series, modular

Question 5

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 6

Find the next term if odd position letters advance by 3, even position numbers follow (i+2)*2: P4, U4, V8, A8, B12

Odd-indexed positions: letter advances by 3 from P, number = (position+2)×2 = 14 at position 5. Next term: E14.

Question 7

Find the next term in the series: N3, O6, P9, Q36

Pattern: Letter increases by 1 each position. Numbers follow: start 2, then +1=3, ×2=6, +3=9, ×4=36, +5=41...
Next: Letter = R, Applying +5 to 36 = 41 → R41

series, position

Question 8

What comes next in the series: B3, D6, H12, P24

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

series, jump

Question 9

Find the next term: Q1, R4, S9, T16

Number is term position squared (1,4,9,16,25). Letter increases by one each time.

series, math transform

Question 10

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 11

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 12

What is the next term in the sequence: E3, G6, I9, K2, M5?

Letters advance by 2 (starting E), digits advance by 3 (mod 10).

multi_skip, double_encode

Question 13

Find the next group in the series: KL1213, MN1415, PQ1617

Groups: Letter steps follow Fibonacci (1,2,3,5), numbers increase by 2 each time. Next is UV1819.

series, grouped

Question 14

Fill in the missing term: X11, V9, T7, ?, P3

Letters move back by 2; numbers -2 each time.

series, reverse

Question 15

Find the next group in the series: JK1213, LM1415, OP1617

Groups: Letter steps follow Fibonacci (1,2,3,5), numbers increase by 2 each time. Next is TU1819.

series, grouped

Question 16

Find the missing term in the series: B2, E3, H4, ?, N6

Each step adds 3 to letter and 1 to number.
The missing term comes fourth: K5.

series, missing term

Question 17

Find the next term in the series: B1, E4, H7, K10

This series alternates letters and numbers, each increasing by 3.
Last term: K10 → next: N13.

series, next term

Question 18

Find the next term: K1, L4, M9, N16

Number is term position squared (1,4,9,16,25). Letter increases by one each time.

series, math transform

Question 19

What comes next in the hybrid series: E6, J12, Q24, Z48

Letters move by steps: 3, 5, 7, 9, numbers double each time. Next step +11 for letter, ×2 for number.

series, hybrid

Question 20

Find the next term if odd position letters advance by 3, even position numbers follow (i+2)*2: O4, T4, U8, Z8, A12

Odd-indexed positions: letter advances by 3 from O, number = (position+2)×2 = 14 at position 5. Next term: D14.
