What is the sum of odd numbers from 110 to 153? Here we will show you step-by-step how to calculate the sum of odd numbers from 110 to 153.
Step 1) We start by finding the first (F) and last (L) odd numbers from 110 to 153. It is easy to do that by simply looking at the numbers. The first odd number is 111, and the last odd number is 153.
F = 111
L = 153
Step 2) Next, we calculate the total odd numbers (T) there are from 110 to 153, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (153 - 111 + 2) ÷ 2
T = 44 ÷ 2
T = 22
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of odd numbers from 110 to 153, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (22 ÷ 2) × (2 × 111 + (2 × (22 - 1))
Sum = 11 × (222 + 42)
Sum = 11 × 264
Sum = 2904
Sum of odd numbers from 110 to 153 = 2904
