First 50 odd natural numbers are: 1, 3, 5, 7, ... First term (a) = 1 Common difference (d) = 3 – 1 = 2 Now, S n = n 2 2 a + n-1 d S 50 = 50 2 2 a + 50-1 d = 25 2 1 + 49 2 = 25 2 + 98 = 25 × 100 = 2500 Hence, the sum of first 50 odd natural numbers is 2500.
The below workout with step by step calculation shows how to find what is the sum of first 50 odd numbers by applying arithmetic progression. It's one of the easiest methods to quickly find the sum of given number series.
31 Ιουλ 2023 · From the above evaluation, we can prove that the formula to find the sum of the first n odd numbers is n x n or n 2 . For instance, if we put n = 21, then we have 21 x 21 = 441, which is equal to the sum of the first 21 odd numbers.
The formula for finding the sum of the first 50 odd numbers is (n/2)(2a + (n-1)d), where n is the number of terms (in this case, 50), a is the first term (1), and d is the common difference (2). 2. How do you know if a number is odd?
Starting from 1, we have the odd natural numbers in the following sequence: 1, 3, 5, ………. (2n-1) The sum of the first natural number is 1. Sum of first two natural numbers is 1 + 3 = 4 = 2*2. Sum of first three natural numbers is 1 + 3 + 5 = 9 = 3*3. Sum of first four natural numbers is 16 = 4*4.
