The geometric sequence formula will refer to determining the general terms of a geometric sequence. In a Geometric Sequence each term is found by multiplying the previous term by a constant. So 1 2 4 8 16.
The normal form of a geometric sequence is in the form of a ar ar² ar³ ar4 and so on.
So if you were wondering how exactly you would work out how much money youll have in there in a few years this article will help you find out. The formula to find the sum of the first n terms of a geometric sequence is a times 1 minus r to the nth power over 1 minus r where n is the number of terms we want to find the sum for a our beginning term of our sequence and r our common ratio. The geometric sequence formula will refer to determining the general terms of a geometric sequence. When you need to find the n-th term in any geometric sequence the formula to use is a n ar n-1 where the common ratio r and the initial value a will be given.
