Determine the number of terms in gp if a1 3
WebSolution: To find: Common ratio. 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 …

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). WebDec 5, 2024 · 1. Identify the first term in the sequence, call this number a. [2] 2. Calculate the common ratio (r) of the sequence. It can be calculated by dividing any term of the geometric sequence by the term preceding it. [3] 3. Identify the number of term you wish to find in the sequence.
Weba = First term of the series r = the common ratio n (exponent) = number of terms. As an example: What is the sum of the 4,16,64,256? The common ratio is 4, as 4 x 4 is 16, 16*4 = 64, and so on.
