Arithmetic

Consider .... 15 + 14N

If N = 1, we have 29 for the first term

If N = 2, we have 43 for the second term

etc.

it is an AP if T 2 - T 1 = T 3 - T 2 = T 4 - T 3 = .... = d

now 43-29 = 57-43 = 71-57 = 14 therefor it is an AP and the common difference is d=14

If it had been a GP then
T 2 / T 1 = T 3 / T 2 = T 4 / T 3 = .... = r
