In an A.P., given a 12 = 37, d = 3, find a and S 12 .

By formula, a n = a + (n - 1)d Given, ⇒ d = 3 ⇒ a 12 = 37 ⇒ a + 3(12 - 1) = 37 ⇒ a + 3(11) = 37 ⇒ a + 33 = 37 ⇒ a = 4. By formula, S n = Substituting values we get : Hence, a = 4 and S 12 = 246.

In an A.P., given a = 5, d = 3, a_n = 50, find n and S_n.
