In
order to solve for a nth term in an arithmetic sequence, we use the formula
written as:
an = a1 + (n-1)d
where an is the nth term, a1 is the first value in the sequence, n is the term
position and d is the common difference.
First, we need to calculate for d from the given values above.
d=11-8=3
at n=100
an = a1 + (n-1)d
a100 = 11 + (100-1)3
a100 = 308
