Algorithms Quiz | SP2 Contest 1 | Question 17

Look at the below series:

1 = 1,  2 = 5,   3 = 13,  4 = ?,  5 = 61

Choose the correct value for “?” from the below options:
(A) 39
(B) 29
(C) 34
(D) 36

Answer: (B)
Explanation: If we look at the numbers at the R.H.S of each term of the series the gap in between them is doubled at each succession. So 5 – 1 = 4, 13 – 5 = 8, 29 – 13 = 16, 61 – 29 = 32
