What is the sum of odd numbers from 88 to 176? Here we will show you step-by-step how to calculate the sum of odd numbers from 88 to 176.
Step 1) We start by finding the first (F) and last (L) odd numbers from 88 to 176. It is easy to do that by simply looking at the numbers. The first odd number is 89, and the last odd number is 175.
F = 89
L = 175
Step 2) Next, we calculate the total odd numbers (T) there are from 88 to 176, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (175 - 89 + 2) ÷ 2
T = 88 ÷ 2
T = 44
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of odd numbers from 88 to 176, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (44 ÷ 2) × (2 × 89 + (2 × (44 - 1))
Sum = 22 × (178 + 86)
Sum = 22 × 264
Sum = 5808
Sum of odd numbers from 88 to 176 = 5808
