What will come in the place of question-mark (?) in the series “2, 7, 14, 23, ?, 47” ?

1. 28
2. 34
3. 31
4. 38

Correct Option: B

We follow the given below pattern in given series :
First term = 2
Second term = First term + 5 = 2 + 5 = 7
Third term = Second term + 7 = 7 + 7 = 14
Fourth term = Third term + 9 = 14 + 9 = 23
Fifth term = Fourth term + 11 = 23 + 11 = ?
∴ ? = 34
Simillarly , we can find other next term of given series.
