{29, 27, 25, 23, 21, …}

{ -1, 2, -4, 8, -16...}

Step-by-step explanation:

Common ratio : the constant pure number you get when you divide a term to the one before it.

thus, 2 ÷ -1 = -2

to check if the common ratio is -2 , divide each terms in front by the one before it.

... 8 ÷ 4 = -2 we got -2 again so the common ratio of this geometric progression is -2.
