What is the sum of odd numbers from 1 to 114? Here we will show you step-by-step how to calculate the sum of odd numbers from 1 to 114.
Step 1) We start by finding the first (F) and last (L) odd numbers from 1 to 114. It is easy to do that by simply looking at the numbers. The first odd number is 1, and the last odd number is 113.
F = 1
L = 113
Step 2) Next, we calculate the total odd numbers (T) there are from 1 to 114, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (113 - 1 + 2) ÷ 2
T = 114 ÷ 2
T = 57
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of odd numbers from 1 to 114, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (57 ÷ 2) × (2 × 1 + (2 × (57 - 1))
Sum = 28.5 × (2 + 112)
Sum = 28.5 × 114
Sum = 3249
Sum of odd numbers from 1 to 114 = 3249
