In an arithmetic sequence, the nth term an is given by the formula an=a1+(n−1)d, where a1is the first term and d is the common difference. similarly, in a geometric sequence, the nth term is given by an=a1•rn−1.
use these formulas to determine the indicated term in the given sequence.
the 19th term of 19,42,65,88
