Find the nth term of this sequence:

Find the nth term of this sequence:  8 15 22 29 36

$\begin{array}{lcrrcl} a_0 &=& 1 & & &=& 1+0\cdot 7 \\ && &+7& \\ a_1 &=& 8 & & &=& 1+1\cdot 7 \\ && &+7& \\ a_2 &=& 15 & & &=& 1+2\cdot 7 \\ && &+7& \\ a_3 &=& 22 & & &=& 1+3\cdot 7 \\ && &+7& \\ a_4 &=& 29 & & &=& 1+4\cdot 7 \\ && &+7& \\ a_5 &=& 36 & & &=& 1+5\cdot 7 \\ \dots \\ \mathbf{a_n} && & & &\mathbf{=}& \mathbf{1+n\cdot 7} \\ \end{array}$

The nth term is given by :

a_n = a₁ + d(n - 1)   =  8 + 7(n - 1)
