The Geometric Mean is a special type of average. Google Classroom Facebook Twitter. What is the geometric mean of 4839 and 17.
If the sequence has a definite number of terms the simple formula for the sum is.
Infinite Geometric Series To find the sum of an infinite geometric series having ratios with an absolute value less than one use the formula S a 1 1 r where a 1 is the first term and r is the common ratio. Test for a geometric sequence. As the index increases each term will be multiplied by an additional factor of 2. We can find the sum of all finite geometric series.
