What is the sum of odd numbers from 6 to 44? Here we will show you step-by-step how to calculate the sum of odd numbers from 6 to 44.
Step 1) We start by finding the first (F) and last (L) odd numbers from 6 to 44. It is easy to do that by simply looking at the numbers. The first odd number is 7, and the last odd number is 43.
F = 7
L = 43
Step 2) Next, we calculate the total odd numbers (T) there are from 6 to 44, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (43 - 7 + 2) ÷ 2
T = 38 ÷ 2
T = 19
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 44, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (19 ÷ 2) × (2 × 7 + (2 × (19 - 1))
Sum = 9.5 × (14 + 36)
Sum = 9.5 × 50
Sum = 475
Sum of odd numbers from 6 to 44 = 475
