Q 19) If the sum of three numbers in an A.P. is 9 and their product is 24, then numbers are
a) 2, 4, 6
b) 1, 5, 3
c) 2, 8, 4
d) 2, 3, 4
Ans: d
Explanation: Reason: Let three numbers be a – d, a, a + d
∴ a – d + a + a + d = 9
⇒ 3a = 9 ⇒ a = 3
Also (a – d) . a . (a + d) = 24
⇒ (3 -d) .3(3 + d) = 24
⇒ 9 – d² = 8
⇒ d² = 9 – 8 = 1
∴ d = ± 1
Hence numbers are 2, 3, 4 or 4, 3, 2

(a) 0
(b) 1
(c) -1.
(d) 2
Ans: a
Explanation : Let common difference of A.P. be d
∴ b = a + d, c = a + 2d, d = a + 3d and e = a + 4d
Given equation a-4b + 6c-4d + c
= a – 4(a + d) + 6(a + 2d) – 4(a + 3d) + (a + 4d)
= a – 4a – 4d + 6a + 12d – 4a – 12d + a + 4d = 8a – 8a + 16d – 16d = 0
