# Easy but tricky math riddle

Can you solve this?

2 = 5
3 = 12
4 = 28
5 = ??￼

SherlockHolmes Expert Asked on 23rd December 2016 in

2 = 5        [2^2 + (2^0) ]

3 = 12     [3^2 + (3^1 x 2^0)]

4 = 28     [4^2 + (2^2 x 3^1)]

5 = 133  [5^2  + (3^2 x 2^2)]

For even number

n = n^2 + (2^n-2 x 3^n-3)  for all n>2

For odd number

n = n^2 + (3^n-2 x 2^n-3)  for all n>1

Explanation-
As, 2 = 5
So, 5 will be equal to 2

The moment you say 2 = 5, the ‘=’ sign has lost its meaning of “equality”. Hence, the law of equality can’t be applied here.
