If a, b and c be there distinct real numbers in G.P and a + b + c = xb, then x cannot be:
If a, b and c be there distinct real numbers in G.P and a + b + c = xb, then x cannot be:
, b, br G.P (
Given a + b + c = xb
b/r + b + br = xb
b = 0 (not possible)
Or 1 + r + = x
x −1 = r+
x −1 > 2 or x−1<−2
x > 3 or x < −1
So x cannot be 2.
