Question

Find the general term set {8,12,16, 24....}

Answer 1

well its an arithmetic sequence since you add 4 all the time...

so you can use the formula for the general term

\[a{_n} = a + (n - 1)\times d\]

a = 1st term, n = number of terms and d is the common difference

in your question a = 8 and d = 4

just substitute and evaluate
