1.	If the 3rd and 9th term of an Ap is 4 and -8 respectively which term of this Ap is zero
Answer» Please reply me a+2d = 4 …(1)a+8d = -8 …(2)Deduct (1) from (2), to get6d = -12, or d = -2.From (1), a = 4–2d = 4+4 = 8.So the numbers of the AP are- 8, 6, 4, 2, 0, -2, -4, -6, -8.So the 5th term is zero.
