In a g.p. a8 192 r 2 then find a12
WebThis is a geometric sequence since there is a common ratio between each term. In this case, multiplying the previous term in the sequence by 2 2 gives the next term. In other words, an = a1rn−1 a n = a 1 r n - 1. Geometric Sequence: r = 2 r = 2 This is the form of a geometric sequence. an = a1rn−1 a n = a 1 r n - 1 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) …

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.
Weba_{8} = 192 and r = 2. Then, by the formula \begin{array}{l} a_{n}=a r^{n-1} \\ a_{8}=a r^{8-1} \\ 192=a(2)^{8-1} \\ 192=a(2)^{7} \\ a=192 / 2^{7} \end{array} a = 192/128. a = 3/2. Now, …
