Find a formula for the general term a_n of the sequence, assuming that the pattern of the first few terms continues. {1, -2/3, 4/9, -8/27,... }

=

Step-by-step explanation:

The sequence has a common ratio between consecutive terms , that is

r = = = = -

This indicates the sequence is geometric with nth term

= a₁

where a₁ is the first term

Here a₁ = 1 and r = - , then

= 1 =

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a

answer: -0.5 would be the most likley outcome
