WebApr 9, 2024 · Answer: The sum of first 50 terms of the AP is 2500 Step-by-step explanation: Given terms of an AP are: 1, 3, 5, 7... The first term i.e, a is = 1 Common Difference = 7 - 5 = 2 To find the sum of given number of terms in an AP, we use the formula:- Here, 'n' is the number of terms in the AP. 'a' represents the first term of the AP. WebSubstracting 1 from 2 we get 2d = 6 d = 3 Further substituting d = 3 in (1) we get 2 = a + 3 a = -1 Number of terms ( n) = 51 First term for the given A.P. ( a) = −1 So, using the formula we get, S n = 51 2 [ 2 ( - 1) + ( 51 - 1) ( 3)] = ( 51 2) [ - 2 + ( 50) ( 3)] = ( 51 2) [ - 2 + 150] = ( 51 2) [ 148] = 3774
