Answer:-
Given:
- a , b , c -- AP
As we know, d (Common difference) = b - a (or) c - b
b - a = c - b
=> a - b = b - c -- equation (1)
And,
- b - b = - c - a
2b = a + c -- equation (2)
- x , y , z -- GP
=> y² = xz -- equation (3)
By using aⁿ * bⁿ = (ab)ⁿ,
Now,
By using a^m* a^n = a^ (m + n)
Hence, LHS = RHS.
