Question

Out of the given options, three are similar in a certain manner. However, one option is NOT like the other three. Select the option which is different from the rest.
1. 30 → 41 → 54
2. 23 → 34 → 49
3. 41 → 52 → 65
4. 47 → 58 → 71

Answer 1

Correct Answer - Option 2 : 23 → 34 → 49

Except for 23 → 34 → 49, in all the options the difference between the first two numbers is 11 and the difference between the second and the third number is 13.

Hence, '23 → 34 → 49' is different from the other three.
