Question

what is a10 for the sequence an = 1 + 3 (n - 1)?

Answer 1

just put the value of n=10 in the formula

\(\large\tt \color{black}{an = 1 + 3 (n - 1)}\)

\(\large\tt \color{black}{a10 = 1 + 3 (10 - 1)}\)

\(\large\tt \color{black}{a10 = 1 + 3 (9)}\)

\(\large\tt \color{black}{a10 = 1 + 27}\)

\(\large\tt \color{black}{a10 = 28}\)
