What is the sum of odd numbers from 6 to 110? Here we will show you step-by-step how to calculate the sum of odd numbers from 6 to 110.
Step 1) We start by finding the first (F) and last (L) odd numbers from 6 to 110. It is easy to do that by simply looking at the numbers. The first odd number is 7, and the last odd number is 109.
F = 7
L = 109
Step 2) Next, we calculate the total odd numbers (T) there are from 6 to 110, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (109 - 7 + 2) ÷ 2
T = 104 ÷ 2
T = 52
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of odd numbers from 6 to 110, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (52 ÷ 2) × (2 × 7 + (2 × (52 - 1))
Sum = 26 × (14 + 102)
Sum = 26 × 116
Sum = 3016
Sum of odd numbers from 6 to 110 = 3016
