What is the value of a 22. The Formula of Geometric Series In general we can define geometric series as n 1 a r n a ar ar2 ar3 arn. A 10 the first term r 3 the common ratio The Rule for any term is.
Geometric sequences are a series of numbers that share a common ratio.
A n a n-1 x 3. What is the common ratio of the sequence below. The formula for a geometric sequence is a n a 1 r n - 1 where a 1 is the first term and r is the common ratio. A 10 the first term r 3 the common ratio The Rule for any term is.
