What is the sum of odd numbers from 94 to 101? Here we will show you step-by-step how to calculate the sum of odd numbers from 94 to 101.
Step 1) We start by finding the first (F) and last (L) odd numbers from 94 to 101. It is easy to do that by simply looking at the numbers. The first odd number is 95, and the last odd number is 101.
F = 95
L = 101
Step 2) Next, we calculate the total odd numbers (T) there are from 94 to 101, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (101 - 95 + 2) ÷ 2
T = 8 ÷ 2
T = 4
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 101, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (4 ÷ 2) × (2 × 95 + (2 × (4 - 1))
Sum = 2 × (190 + 6)
Sum = 2 × 196
Sum = 392
Sum of odd numbers from 94 to 101 = 392
