Question

What is the odd or wrong number in the given series?
2, 9, 28, 65, 126, 216, 344.

Answer 1

i think the answer is 216 bcoz the pattern is something like odd, even, odd, even.....

so in place of 216 an odd no. should have been there.....

Answer 2

Step-by-step explanation:

Given series => 2 , 9 , 28 , 65 , 126 , 216 , 344

The series follows the logic => n^3 + 1

So

t1 = 1^3 + 1 = 2

t2 = 2^3 + 1 = 8 + 1 = 9

but

t6 = 6^3 + 1 = 216 + 1 = 217

Hence 216 is the wrong number in given series
