Correct Answer: 51
Solution :
Given:
12, 15, 20, 27, 38, ?
Add the consecutive prime numbers (starting from 3) to the previous term to obtain the next term.
12 + 3 = 15; 15 + 5 = 20; 20 + 7 = 27; 27 + 11 = 38; 38 + 13 = 51
So, 51 is the missing term in the series. Hence, the third option is correct.
