what is the general formula of geometric sequence. B The variable x can take on any numerical value. For example to find the second term of any sequence we multiply the first term by the common ratio.

But in this case the second term has to be negative an a1 - dn-1. One of them is by using a recursive formula. A n a 1 r n 1 Understanding the nth term of a geometric sequence gets easier if we know the meaning of this term and variables used.
This is a simple arithmetic sequence.
A geometric sequence of an infinite number of terms is shown as aarar2ar3. The following series is geometric. The Formula of Geometric Series In general we can define geometric series as n 1 a r n a ar ar2 ar3 arn Where a is the first term and r is the common ratio for the geometric series. A geometric sequence can be defined recursively by the formulas a1 c an1 ran where c is a constant and r is the common ratio.
