- 18
- 21
Show answer
Answer: A. Two interleaved series: odd positions increase by 3 (10,13,16,19...) and even positions decrease by 3 (30,27,24...); the next term (7th, odd position) is 16 + 3 = 19.
Sample Medium question 6
Find the next number: 1, 4, 9, 18, 35, ?
- 64
- 60

Show answer
Answer: D. The differences between terms are 3, 5, 9, 17 — each difference is (previous difference × 2) − 1. The next difference is 17×2−1 = 33, so the next term is 35 + 33 = 68.
