Question

Determine the ratio of the geometric sequence: 1/16, -1/4, 1,...

Answer 1

• The common ratio of the given sequence is - 4

-------------------------------

Given sequence:

• 1/16, - 1/4, 1, ...

Find the common ratio, the ratio of two consecutive terms:

• r = 1 ÷ (- 1/4) = 1 × (- 4) = - 4

or

• r = - 1/4 ÷ 1/16 = - 1/4 × 16 = - 4
