Answer:

STEP 1:

Find the common ratio:

an = a1rn-1

-625 = -1r 5-1

-625 = -1r4

-625. -1

-------- = --------

-1. -1

625 = r4

5 = r

SECOND STEP: MULTIPLE THE COMMON RATIO TO THE FIRST STEP, TO GET THE SECOND TERM, THEN REPEAT UNTIL YOU SOLVE THE THREE GEOMETRIC MEANS

a2 = -1×5 = -5

a3 = -5×5 = -25

a4 = -25×5 = -125

ANSWER : -5, -25, -125
