Answer – 2
Explanation-
As, 2 = 5
So, 5 will be equal to 2
(Law of Equality)
The moment you say 2 = 5, the ‘=’ sign has lost its meaning of “equality”. Hence, the law of equality can’t be applied here.
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
