Find the next two terms of the series : 2 - 6 + 18 - 54 .............

Question

KnowledgeBoat · Accepted Answer

Since, = -3. Hence, the above series is a G.P. with r = -3 and a = 2. We know that n^th term of G.P., a_n = ar^{n - 1} Next two terms of the series are 5^th and 6^th. ⇒ a₅ = ar⁴ = 2.(-3)⁴ = 2 × 81 = 162. ⇒ a₆ = ar⁵ = 2.(-3)⁵ = 2 × -243 = -486. Hence, the next two terms are 162 and -486.
