Answer by Edwin McCravy(19350) (Show Source): WebFrom the question it is given that,a 8=192 and r=2Then, by the formula a n=ar n−1a 8192a=a=a==ar 8−1192=a(2) 8−1=a(2) 7192/2 7192/1283/2Now,a 12=(3/2)(2) …

n-th Term of a Geometric Sequence - Varsity Tutors

WebNov 22, 2015 · Explanation: a6 = 7 × 2(6−1) = 7 ×32 = 224. hope that helped. Answer link. WebFeb 11, 2024 · There exist two distinct ways in which you can mathematically represent a geometric sequence with just one formula: the explicit formula for a geometric sequence and the recursive formula for a geometric sequence.The first of these is the one we have already seen in our geometric series example. What we saw was the specific, explicit … small hand steamer

WebExample 2: Find the 7 th term for the geometric sequence in which a 2 = 24 and a 5 = 3 . Substitute 24 for a 2 and 3 for a 5 in the formula a n = a 1 ⋅ r n − 1 . a 2 ... Web4 4 , 12 12 , 36 36 , 108 108. This is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 3 3 gives the next term. In other words, an = a1rn−1 a n = a 1 r n - 1. Geometric Sequence: r = 3 r = 3. This is the form of a geometric sequence. an = a1rn−1 a n = a 1 r ... WebIf a 1 , a 2 , a 3 ,....., a n are consecutive terms of an increasing A.
