Write the first five terms of a geometric sequence in which a 1 2 and r3. X 4 10 3 4-1 10 3 3 10 27 270. An interesting result of the definition of the geometric progression is that any three consecutive terms a b and c will satisfy the following equation.
For example suppose the common ratio is 9.
As a simple example lets look at the sequence. Displaystyle r4 r 4 we can find subsequent terms by multiplying. So the recursive formula is. A 10 the first term r 3 the common ratio The Rule for any term is.
