imagine points on a line
(0,14)
(1,18)
(2,22)
(3,26)
(4,30)

and imagine you had to write the equation for this line...can you write the equation for this line?

welshfella · Answer

the general  formula for the nth term is

a + (n - 1)d   where a = first term and d = common difference

so plug in a = 14 and d = 4  and  simplify to get one of the options
