$901.88

Step-by-step explanation:

-20.10 + 1357.48 = 1337.38

1337.38  + 599 = 1936.38

1936.38 - (3*375) = 811.38

811.38  + (45.25*2) = 901.88

$901.88

Hope this helps!

step-by-step explanation:

since the sequence is geometric there is a common ratio r between consecutive terms, that is

r = 4 ÷ - 2 = - 2

r = - 8 ÷ 4 = - 2

r = 16 ÷ 8 = - 2

the next term - 13 must be incorrect as it should be - 32 for the sequence to be geometric.

the first 4 terms are therefore geometric with common ratio r = - 2
