Question

In the question given below three out of the four given sets of numbers follow the same pattern, while the fourth one is different. You have to find out the set that does not follow the pattern of the other three.

• A. 8 (39) 5
• B. 12 (66) 10
• C. 9 (45) 6
• D. 5 (17) 2
• E. None of these

Answer 1

The correct option is D 5 (17) 2

We have,

(a) $8+5=13,13\times 3=39$

(b) $12+10=22,22\times 3=66$

(c) $9+6=15,15\times 3=45$

(d) $5+2=7,7\times 3=21$ which is not equal to $17$.

Hence, (d) is the odd one out.
