Question

The first three terms of a geometric sequence are as follows

-5,-20,-80
Find the next two terms of this sequence; give an exact value (not decimals)

Answer 1

Answer: -1280

Explanation:

in a geometric sequence it either multiplies or divides negatively or positively, in this case -5 to -20 is multiplied 4 positively and so is -20 to -80

then -80x4= -320

-320x4= -1280
