WebThe nth term of a GP is an =128 a n = 128. The first term of the GP is a = 2 a = 2. The common ratio of the GP is r =2 r = 2. Now use the condition if the first and nth term of a GP are a and b respectively then, b =a ⋅rn−1 b = a … WebWe're asked to seek the value of the 100th term (aka the 99th term after term # 1). We're given the first term = 15, therefore we need to find the value of the term that is 99 terms after 15. The arithmetic formula shows this by a+(n-1)d where a= the first term (15), n= # of terms in the series (100) and d = the common difference (-6).

Divide each term by the previous term to determine whether a common ratio exists. 2 1 = 4 2 = 8 4 = 16 8 = 2 2 1 = 4 2 = 8 4 = 16 8 = 2. The sequence is geometric because there is a common multiple, 2, which is called the common ratio. Answer: Common ratio, r = 2.
WebFind the value of n: Given, a 1 = 3 a n = 96 S n = 189. The n t h term of GP is a r n-1. 3 (r n-1) = 96 ⇒ r n-1 = 96 3 ⇒ r n-1 = 32 ⇒ r n = 32 r … (i) Now, S n = a (r n-1) (r-1) ⇒ a (r n …
