Step-by-step explanation:

To solve the exercise you must use the formula shown below:

Where:

You should find  

The formula to find it is:

Where d is the difference between two consecutive terms.

Then:

Substitute it into the first formula. Therefore, you obtain:

Sn = -216

Step-by-step explanation:

We are given the following sequence and we are to find the sum of the given sequence if there are 24 terms in it:

We know that the formula of sum for an arithmetic sequence is given by:

where is the first term (124)and is the last term .

To find , we will use the following formual:

Substituting the given values in the above formula to get the sum:
