Answer
Makes sense
Work Step by Step
Sum of the an arithmetic sequence can be calculated by using formula $S_n=\dfrac{n}{2}(2a_1+(n-1)d)$
Here $S_n$ denotes sum and $a_1$ denotes first term or initial term with $d$ as common difference.
But the given sequence does follow a pattern of same $d$ , this means that the sequence is a arithmetic sequence. Therefore, we can apply the sum formula to calculate the first $50$ terms as we have first term and last term $a_{50}$.
