Question

4. Calculate the sum of 5+(-5)+5+ ... up to 183 terms.​

Answer 1

Step-by-step explanation:

As 1st number of the sequence Or, the first odd number is 5.

Then, all the odd places number will be 5 and as 183rd is an odd place, so the number of that place will also be 5.

Now, From the sequence we can say that the sum of first two terms is 5+(-5)=0.

And in the sequence there are 91 such type two terms and one odd place term that is 183rd term or the last term of the sequence.

As the sum of first two terms is 5+(-5)=0.

So, the sum of such 91 terms will also be 0.

Therefore, the sum of 5+(-5)+5+ ... up to 183 terms

=0+183rd term of the sequence

=0+5=5.

Here is your answer.
