Step-by-step explanation:

The given sequence is:

−282,−266,−250,−234,...

Thus, we have the first term of the sequence is:

And the common difference is:

Now, the sum of the first 51 terms of the given sequence is:

Substituting the given values, we have

which is the required sum of the first 51 terms of the given sequence.
