Question

Write the sum using summation notation, assuming the suggested pattern continues.

16 + 25 + 36 + 49 + ... + n2 + ...

Answer 1

answer choices:

\[\sum_{n=5}^{\infty}n^2 \]


\[\sum_{n=4}^{\infty}n+1^2\]

\[\sum_{n=4}^{\infty}n-1^2\]

\[\sum_{n=4}^{\infty}n^2\]

Answer 2

16 = 4^2
25 = 5^2
36= 6^2
49 = 7^2
You have a sum of the squares of integers starting with 4^2
The pattern is simply n^2, and the starting point is n = 4

Answer 3

so its the last one

Answer 4

yes
