Step-by-step explanation:
Given the general term for calculating the nth term of a sequence;
Sn = n²
Where n is the number of terms.
To find the 99th term of the sequence using the nth term of the sequence;
Since we want to get the 99th term, this means that n = 99. Substituting n = 99 into the formula we will have;
S99 = 99²
S99 = 9,801
Answer:
a = 15
