439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400

see explanation

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

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
