What is the sum of odd numbers from 24 to 134? Here we will show you step-by-step how to calculate the sum of odd numbers from 24 to 134.
Step 1) We start by finding the first (F) and last (L) odd numbers from 24 to 134. It is easy to do that by simply looking at the numbers. The first odd number is 25, and the last odd number is 133.
F = 25
L = 133
Step 2) Next, we calculate the total odd numbers (T) there are from 24 to 134, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (133 - 25 + 2) ÷ 2
T = 110 ÷ 2
T = 55
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of odd numbers from 24 to 134, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (55 ÷ 2) × (2 × 25 + (2 × (55 - 1))
Sum = 27.5 × (50 + 108)
Sum = 27.5 × 158
Sum = 4345
Sum of odd numbers from 24 to 134 = 4345
