Find the 18th term in the arithmetic sequence. 2, 8, 14, 20, 26,

Well first we need to make a function, this is increasing proportionally so we know the equation will be

Now its increasing by 6 for each step in x so

If we plug in when x = 1 and y = 2(the first given term)

Now the arithmetic sequence can sbe represented by

If you plug in 18, well get the 18th term

The 18th term is 104
