You can tell it's an arithmetic sequence because \[ \large a_{n+1} -a_n=5 \]

Arithmetic sequences have the form: \[ a_n = a_1 + (n-1)d \]
anonymous
  • anonymous
In this case \(d = 5\) and \(a_1=1\), so our equation is \[ a_n = 1 + (n-1)5 \]

But that is not the question... your formula is:\[a_n = a_1 + (n - 1)d\]The \(d\) was stated by @wio: \(5\).

So you want to substitute \(n=8\) into the equation to find \(a_8\).

So, the formula is:\[a_n = 1 + 5(n - 1)\]Now substitute \(n = 8\).
