The nth term of an Arithmetic Progression can be written in the form of a linear equation as: an + b. So, the product of two Arithmetic Progressions will have terms of the form pn2 + qn + r where n = 0,1, 2.... Putting n = 0, 1 and 2 we get, r = 192, p + q + r = 360 and 4p + 2q + r = 576 respectively. Solving these three equations we get p = 24 and q = 144. Putting n = 7 and values of p, q, r we get the eighth term as 2376.
