The sum of three terms (numbers) of a G.P. is and their product is 1; the numbers are : 1. and 2 2. and 9 3. and 2 4. and 1

Let three terms of G.P. be . Given, Product of three terms of G.P. = 1 Given, Sum of three terms of G.P. = Let r = Terms : ⇒ , a, ar ⇒ ⇒ 2, 1, . Let r = 2 Terms : ⇒ , a, ar ⇒ ⇒ , 1, 2. Hence, Option 1 is the correct option.
