WebOct 28, 2016 · Recursive formula for a geometric sequence is an = an−1 × r, where r is the common ratio. Explanation: A geometric series is of the form a,ar,ar2,ar3,ar4,ar5 ......................... in which first term a1 = a and other terms are obtained by multiplying by r. Observe that each term is r times the previous term. 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 1 5 1 5 gives the next term. In … WebThe recursive formula to find the n th term of a geometric sequence is: a n = a n-1 r for n ≥ 2 where a n is the n th term of a G.P. r is the common ratio. Recursive Formula for Fibonacci Sequence The recursive formula to find the n th term of a Fibonacci sequence is: a n = a n-1 + a n-2 for n ≥ 2, where a 0 = 1 and a 1 = 1 peaches\\u0026cream yarn
