Question

Need help with this problem only find the common difference

Answer 1

Given the arithmetic sequence:

`\begin{gathered} f(1)=5 \\ f(n)-f(n-1)=12 \end{gathered}`

The common difference of an arithmetic sequence is the constant difference between two consecutive elements. In this case, f(n) and f(n - 1) are two consecutive elements, and we already know the difference between them (12).

Then:

`\text{Common difference }=12`
