The sum of first 8 terms of series is -130208
<em><u>Solution:</u></em>
Given that,
2 - 10 + 50 - 250 , ....
n = 8
Find the common ratio between a term and its previous term

Thus common ratio is same
This is a geometric series
<em><u>The sum of terms of geometric sequence is given as:</u></em>

Where,
r is the common ratio
n is the nth term
is the first term of series
From series,

Therefore,

Thus sum of first 8 terms of series is -130208
