Evaluate the geometric series. Please help me!!

o-na [289]

Answer:

- 85

Step-by-step explanation:

The n th term of a geometric series is

$a_{n}$ = a $(r)^{n-1}$

where a is the first term and r the common ratio

1 $(-2)^{n-1}$ ← is the n th term of a geometric series

with a = 1 and r = - 2

The sum to n terms of a geometric series is

$S_{n}$ = $\frac{a(r^{n}-1) }{r-1}$

= $\frac{1((-2)^{8}-1 }{-2-1}$

= $\frac{256-1}{-3}$

= $\frac{255}{-3}$

= - 85

Mkey [24]

Answer:

$2^{11}$

Step-by-step explanation:

<u>Key indices rule: When dividing powers, subtract the indices and keep the base numbers constant.</u>

<u /> $\frac{2^{3} }{2^{-8} }$ Based on the rule above, the indices are determined by 3--8, which is 11.

The base number is kept constant.

Therefore, the answer is $2^{11}$ .
