Answer:

The answer is

-524288

Step-by-step explanation:

For an nth term in a geometric sequence

[tex]a(n) = a ({r})^{n - 1} [/tex]

where a is the first term

r is the common ratio

n is the number of terms

From the question

a = 2

r = - 8/2 = - 4

n = 10

So we have

[tex]a(10) = 2( - 4)^{10 - 1} [/tex]

[tex] = 2( - 4)^{9} [/tex]

We have the final answer as

-524288

Hope this helps you
