Explanation:

Sol. Ans.(c). The given sequence is: 14, 18, 20, 24, 30, 32, …. We are told that by applying an operation, we get prime numbers from this series.

We can see that by subtracting 1 from each term, we will get a sequence of primes.

14 – 1 = 13; 18 – 1 = 17; 20 – 1 = 19; 24 – 1 = 23; 30 -1 = 29; 32 – 1 = 31.

So the next term will be 38 – 1 = 37 which is also a prime number.

So the correct option is (c).
