we are given
geometric sequence -36, 6, -1, 1/6, ...
first term is -36

now, we can find common ratio


now, we can find nth term

now, we can plug values
and we get

now, we can find 5th term , 6th term, 7th term
fifth term:


sixth term:


seventh term:


so, next terms are
,

.............Answer
Well, its 10 for 4. so 8 is 20, 12 is 30, 16 is 40 20 is 50, and 24 is 1 hour, 2 tabels is half the time so 5 min... so it would take -1 hour and 5 min
<span>x^2-2x-24 = (x - 6)(x + 4)
cause
</span>(x - 6)(x + 4)
= x^2 - 6x + 4x - 24
= x^2 - 2x - 24
answer
(x - 6)(x + 4)
hope it helps
D) 8.17 x 10^8
910000000 - 93000000 = 817000000
817000000 ---> 8.17 x 10^8
