Answer 1

9594

Explanation:

The sum of the arithmetic sequence where the first term is 6 and the last term is 363 is 9594.

Sum of an arithmetic sequence: Sn=n2(a1+an), where a1 is the first term and an is the last term.

Sigma notation: 52∑k=6=522(6+363)=9594

Answer 2

Using formula:
sum = (n/2)( a + L)
n = 52 ,a = 6 and L = 363
