Question

Choose the correct alternative that will complete the given series.

148, 150, 153, 158, 165, ?

1. 177
2. 176
3. 186
4. 175

Answer 1

Correct Answer - Option 2 : 176

The pattern followed here is:

Each number is adding with prime number.

148 + 2 = 150,

150 + 3 = 153, 

53 + 5 = 158,

158 + 7 = 165,

Similarly,

165 + 11 = 176.

Hence, 176 is the answer.

The first 25 prime numbers (all the prime numbers less than 100) are: 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97.

Therefore, every prime number other than 2 is an odd number and is called an odd prime.
