Jacob has 75 cookies.

He gave 2 cookies to each student.

Complete the table:

$\begin{array}{cc}\text{Number of student arrived}&\text{Number of cookies left}\\1&75-2=73\\2&73-2=71\\3&71-2=69\\...&...\end{array}$

Let n be the number of students. After nth student arrived Jacob had left

$g(n)=75-2n$

cookies.

This is an arithmetic sequence with

$g_1=g(1)=73\\ \\d=-2$

Thus,

$g_{n}=g_{n-1}-2\\ \\g(n)=g(n-1)-2$
