Correct Answer: 13 – 2199
Solution :
Let's check each option –
First option:
13 – 2199; 13
3
+ 1 = 2197 + 1 = 2198 ≠ 2199
Second option:
14 – 2745; 14
3
+ 1 = 2744 + 1 = 2745
Third option:
12 – 1729; 12
3
+ 1 = 1728 + 1 = 1729
Fourth option:
17 – 4914; 17
3
+ 1 = 4913 + 1 = 4914
So, only the first option doesn't follow the same pattern as followed by the given set of numbers. Hence, the first option is correct.
