Xn 10 3n-1 So the 4th term is. You want to find a formla for a sequence define by u n 1 a u n b for all n 0. The following series is geometric.
It follows the formula an a1 dn-1.
The following series is geometric. The idea is to try to reduce to geometric sequences. Recursive formula for geometric sequence helps us find the next term of the sequence by multiplying the previous term with a common ratio. For example to find the second term of any sequence we multiply the first term by the common ratio.
