#### Question No 22

The sum of how many terms of the series 6 + 12 + 18 + 24 + ... is 1800 ?

Solution!
This is an A.P. in which a = 6, d = 6 and Sn = 1800
Then, n/2[2a + (n - 1)d] = 1800
n/2[2 x 6 + (n - 1) x 6] = 1800
3n (n + 1) = 1800
n(n + 1) = 600
n2 + n - 600 = 0
n2 + 25n - 24n - 600 = 0
n(n + 25) - 24(n + 25) = 0
(n + 25)(n - 24) = 0
n = 24
Number of terms = 24.

#### Question No 24

(22 + 42 + 62 + ... + 202) = ?

Solution!
(22 + 42 + 62 + ... + 202) = (1 x 2)2 + (2 x 2)2 + (2 x 3)2 + ... + (2 x 10)2
= (22 x 12) + (22 x 22) + (22 x 32) + ... + (22 x 102)
= 22 x [12 + 22 + 32 + ... + 102]            Ref: (12 + 22 + 32 + ... + n2) =1/6 n(n + 1)(2n + 1)
=(4 x 1/6x 10 x 11 x 21)
= (4 x 5 x 77)= 1540.
