What are the next three terms of the following sequence? 8, 40, 200, 1000 what are the next three terms of the following sequence? -10, 20, -40, 80 what are the next three terms of the following sequence? -2, 4, -8, 16

we know that given terms were i geometric progression.

which means common ratio is same between two consecutive terms .

here we have 8,40,200,1000.

we know that common ratio =second term/first term =40/8=5.

so each and every terms is multiplied by 5 to get next term for this series the term after 1000 is 5000 =1000*5.

in part b we have another series which is having common ratio of -2.

so we need to multiply with -2 to find next term.

80*(-2)=-160.

for part c the common ratio is -2 .

so we need to multiply with -2 *previous term =-2*16 =-32.

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844
