A. 99

B. 131

C. 137

D. 124

Answer: Option B

Solution(By Examveda Team)

Logic:
Last Term *2 - 3 = Next Term.

First Term = 7
Second Term = 7 * 2 -3 = 11
Third Term = 11 * 2 - 3 = 19
Fourth Term = 19 * 2 - 3 = 35
Fifth Term = 35 * 2 - 3 = 67
Sixth Term = 67 * 2 -3 = 131
Alternative Solution :
Last term + 2n = Next Term
First Term = 7
Second Term = 7 + 22 = 11
Third Term = 11 + 23 = 19
Fourth Term = 19 + 24 = 35
Fifth Term = 35 + 25 = 67
Sixth Term = 67 + 26 = 131
