Answer:
6
Step-by-step explanation:
We need to evaluate :-
Here the
is the sum operator . And here we need to find the sum from n = 1 to n = 4 . We can write it as ,
Now we know that for odd powers of -1 , we get -1 and for even powers we get 1 . Therefore ,
Now add the terms inside the brackets and then multiply it with the number outside the bracket . We will get ,
<u>Hence</u><u> the</u><u> </u><u>required</u><u> answer</u><u> is</u><u> </u><u>6</u><u>.</u>
