Question

KnowledgeBoat · Accepted Answer

Common ratio, . So, the above sequence is a G.P. with r = 3. Let there be n terms. m^th term from end is (n - m + 1)^th term from starting. So, 3^rd term from end is (8 - 3 + 1) = 6^th term from starting. a₆ = ar⁵ = = = 2 × 9 = 18. Hence, 3^rd term from end is 18.
