Question

7,19,31,43,55 Write a simplified expression for the right of the equation that can be used to find the nth term in the sequence?

Answer 1

$\begin{gathered} \text{From the sequence, i have a = 7, d = 12} \\ \text{Thefore using the nth term we have: T}_{n\text{ }}=a\text{ +(n-1)d} \\ \text{ = 7 +(n - 1)12} \\ \text{ = 7 + 12n - 12} \\ \text{ = 12n - 5} \end{gathered}$
