Odd one out of the given four alternatives...?

⏹ Explanation:

We have to find the relation between these numbers. What's common in between them. If u analyse carefully, You will find that the given numbers are in the form n² + n.

• 56 = 7² + 7
• 72 = 8² + 8
• 90 = 9² + 9

But, 64 is 8², it's not in the form of n² + n, hence the odd one out of the four alternatives is 64.

$\mathbb{\fbox{\fbox{\green{64}}}}$

Step-by-step explanation:

$\huge\sf\pink{Here,}$

$we \: used \: = {n}^{2} + n$

$\huge\tt\blue{Then, }$

$56 = {7}^{2} + 7 \\ 72 = {8}^{2} + 8 \\ 90 = {9}^{2} + 9 \\ 64 = {8}^{3}$

So, D) 64 is the odd one.
