How to Find the Sum of First 50 Odd Numbers? 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.
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.
$P(n):$ the sum of the first $n$ odds is $n^2$. This is a proposition about the natural numbers; so we can now proceed to see if it can be proved by mathematical induction. First up is the base case , $P(1)$.
The summation formulas are used to find the sum of any specific sequence without actually finding the sum manually. For example, the summation formula of finding the sum of the first n odd number is n 2. Using this, we can say that the sum of the first 30 odd numbers is 1 2 + 3 2 + ... (30 numbers) = 30 2 = 900.
