Question

Pls do this question with number wise pls

Answer 1

If n is an odd number then it must be look like this equation:
25-1=24
24 is divisible by 8....
Equation=n²-1
n is odd no. Then one by one we put odd no. In the place of n like this:
(1)²-1=>1-1=0[equation.1]
(3)²-1=>9-1=8[equation.2]
(5)²-1=>25-1=24[equation.3]
So, equation 1 will be not divisible by 8 but equation 2 and 3 is divisible by 8....
It's step by step instructions....
