What should come in place of ‘?’ in the given sequence?
2 3 10 39 172 ? ​​

2 3 10 39 172 ?

Logic: Each number is obtained by multiplying the previous number by an increasing sequence (1, 2, 3, 4, 5...) and then adding the square of that multiplier.

2 × 1 + 1 = 2 + 1 = 3
3 × 2 + 4 =  6 + 4 = 10
10 × 3 + 9 = 30 + 9 = 39
39 × 4 + 16 =  156 + 16 = 172
172 × 5 + 25 = 860 + 25 = 885

Thus, the correct answer is (c).
