Question

A teacher gave his students the four graphs below. Which graph represents a geometric sequence?

Answer 1

The arithmetic sequences always graph as points along a line.

In a geometric sequence, each term is equal to the previous term, multiplied (or divided) by a constant.

The  exponential functions have a very special property:

equal changes in the input cause the output to be successively multiplied by a constant.

Geometric sequences also have this same special property:geometric sequences always graph as points along the graph of an exponential function.

The sequence 6.25,12.5,25,50,100 is a geometric sequence  so its graph will represent a geometric sequence.

Answer 2

The answer is

graph A
