• arithmetic

• geometric

• neither

Find the common ratio for the geometric sequence.

• 1

• -1

• 7

• -7

Write the explicit formula for the geometric sequence.

• a_n = 7(1)ⁿ

• a_n = 7(-1)ⁿ

• a_n = 7(-1)^n-1

• a_n = -1(7)^n-1

Find the common ratio for the geometric sequence.

• -4

• 1/4

• -1/4

Find the common ratio for the geometric sequence.

• 2/3

• 3/2

• -2/3

• -3/2

Write the explicit formula for the geometric sequence.

• a_n = 162(2/3)^n-1

• a_n = (2/3)(162)^n-1

• a_n = 162(3/2)^n-1

• a_n = 162 + (n-1)(-54)

Find the common ratio for the geometric sequence.
