Question

Find the first,fourth,and tenth terms of the arithmetic sequence described by the given rule. A(n) = 12+(n-1)(3)

Answer 1

\[a_n = 12+(n-1)(3)\]The first term is \(a_1\) and \(n = 1\):
\[a_1 = 12 + (1-1)(3) = 12 + 0(3) = 12\]
You should be able to find \(a_4, a_{10}\) which have values of \(n = 4, n=10\) respectively (I hope you see the relationship!)

Answer 2

Thank you
