what is the formula of geometric sequence brainly. 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. So 1 2 4 8 16.

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. - Voiceover The geometric sequence a sub i is defined by the formula where the first term a sub one is equal to negative 18 and then every term after that is defined as being so a sub i is going to be two times the term before that. Is geometric because each step multiplies by two.
