A) Given:

The sequence is,


1,2,3,4,5,6,7,8,…

To find: The term-to-term rule

Since the given sequence has the common differnce 1.

So, it is of the arithmetic sequence.

Therefore, let us take


a_1=1

Then the second term will be,


\begin{gathered} a_2=a_1+1 \\ =1+1 \\ =2 \end{gathered}

The third term will be,


\begin{gathered} a_3=a_2+1 \\ =2+1 \\ =3 \end{gathered}

And so on.

So, the term to term rule must be,


a_n=a_(n-1)+1

Final answer: The term to term rule is,


a_(n)=a_(n-1)+1
