What is the sum of odd numbers from 62 to 63? Here we will show you step-by-step how to calculate the sum of odd numbers from 62 to 63.
Step 1) We start by finding the first (F) and last (L) odd numbers from 62 to 63. It is easy to do that by simply looking at the numbers. The first odd number is 63, and the last odd number is 63.
F = 63
L = 63
Step 2) Next, we calculate the total odd numbers (T) there are from 62 to 63, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (63 - 63 + 2) ÷ 2
T = 2 ÷ 2
T = 1
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of odd numbers from 62 to 63, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (1 ÷ 2) × (2 × 63 + (2 × (1 - 1))
Sum = 0.5 × (126 + 0)
Sum = 0.5 × 126
Sum = 63
Sum of odd numbers from 62 to 63 = 63
