Front

Find the common ratio for the geometric sequence. Options: 10, 1/2, 2, 4

Back

2

Front

Find the common ratio for the geometric sequence.

Back

-1

Front

Write the explicit formula for the geometric sequence. Options: a_n = 4(3)^n-1, a_n = 3(4)^n-1, a_n = -4(3)^n-1, a_n = 3(-4)^n-1

Back

a_n = 3(-4)^n-1

Front

Given the sequence: 125, 25, 5, .... Write the rule a_n using the geometric sequence formula.

Back

a_n = (125)(1/5)^(n-1)

Front

Find the first four terms of the sequence given the rule:
a_n = 4(5)^n-1

Back

4, 20, 100, 500
