Ageometric sequence is defined by the equation an=(2)5-2n. what are the first three terms of the sequence and what is the common ratio, r?

First term = (2)5^(-2*1) =2/25

2nd term = (2)5^(-2*2) = 2/ 625

3rd term = 2(5)^(-2*3) = 2/ 15625

If we divide the 3rd term by the 2nd term or the 2nd term by the first we get the common ratio

Common ratio = 1/25 or 0.04 as a decimal fraction.

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

assuming you mean addition: addition and subtraction are reverse operations.
