Integers between 50 and 500 that divisible by 6 |
|
Answer» Step-by-step EXPLANATION: The required A.P is 56, 63, 70,.........., 497 a = 56 d = T2 - T1 d = 63 - 56 d = 7 Tn = a +(n-1)d 497 = 56 + (n-1)7 497-56 = (n-1)7 441/7 = n-1 63 +1 = n n = 64 terms Sn = n/2 (a+l) S 64 = 64/2 ( 56 + 497) S 64 = 32 x 553 S 64 = 17,696 Hence the SUM of all INTEGERS between 50 and 500 divisible by 7 is 17,696. 4.7 Read more on Brainly.in - brainly.in/question/3068215#readmore |
