WebSolution For a, b, c to be in GP, we must have b a= c b= r or b a= c b= 1 r Case I When b a= c b= r In this case, b = ar and c = br. ∴ a−b b−c = a−ar b−br = a(1−r) b(1−r) = a b Case II When b a= c b= 1 r In this case, a = br and b = cr. ∴ a−b b−c = br−b cr−c = b(r−1) c(r−1) = b c Hence, the value of (a−b b−c) is a b or b c.
