What is the sum of odd numbers from 94 to 146? Here we will show you step-by-step how to calculate the sum of odd numbers from 94 to 146.
Step 1) We start by finding the first (F) and last (L) odd numbers from 94 to 146. It is easy to do that by simply looking at the numbers. The first odd number is 95, and the last odd number is 145.
F = 95
L = 145
Step 2) Next, we calculate the total odd numbers (T) there are from 94 to 146, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (145 - 95 + 2) ÷ 2
T = 52 ÷ 2
T = 26
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of odd numbers from 94 to 146, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (26 ÷ 2) × (2 × 95 + (2 × (26 - 1))
Sum = 13 × (190 + 50)
Sum = 13 × 240
Sum = 3120
Sum of odd numbers from 94 to 146 = 3120
