What is the common ratio of the geometric sequence below? –2, 4, –8, 16, –32,

The common ratio of the sequence is –2, 4, –8, 16, –32, ... is - 2.

Step-by-step explanation:

Geometric sequence is written as

a , ar , ar² , ar³,........

Where a is the first term and r is the common ratio.

As given the sequence

–2, 4, –8, 16, –32, ......

a = - 2

ar = 4

Thus

r = -2

Therefore the common ratio of the sequence is –2, 4, –8, 16, –32, ... is - 2.
