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 =

x/3-10=8

x/3=18

x=48

10 b/c 5*2 =10
