Number Series Q.26
0. Find the wrong number in the sequence.
125, 127, 130, 135, 142, 153, 165
- Option : D
- Explanation : Prime number (numbers that are divisible by 1 and
themselves only) starting with 2 are being added to each
number to get the subsequent numbers.
Thus, the sequence of numbers can be read as 125, 125 + 2, 127 + 3, 130 + 5, 135 + 7, 142 + 11, and 153 + 13.
Hence, the last number should be 166.
