Question

Identify the 8th term of the geometric sequence -2, -12, -72 ...

Answer 1

you multiply times 6 every time, so the 8th term would be \(\normalsize\color{black}{ (-2) \times 6^{(8-1)} }\)

Answer 2

unn -559872

Answer 3

howd you get the 8-1

Answer 4

because to get to the 2 term you add the difference 1 time,
to get to the 4th term you add the difference five times

Answer 5

so to get the 8th term, you add 7 the difference times.

Answer 6

ohhh

Answer 7

In this case (in geometric sequence) you multiply the common ratio 7 times to get to the 8th term.

Answer 8

gotcha

Answer 9

okay ....
