What is the sum of odd numbers from 62 to 192? Here we will show you step-by-step how to calculate the sum of odd numbers from 62 to 192.
Step 1) We start by finding the first (F) and last (L) odd numbers from 62 to 192. It is easy to do that by simply looking at the numbers. The first odd number is 63, and the last odd number is 191.
F = 63
L = 191
Step 2) Next, we calculate the total odd numbers (T) there are from 62 to 192, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (191 - 63 + 2) ÷ 2
T = 130 ÷ 2
T = 65
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of odd numbers from 62 to 192, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (65 ÷ 2) × (2 × 63 + (2 × (65 - 1))
Sum = 32.5 × (126 + 128)
Sum = 32.5 × 254
Sum = 8255
Sum of odd numbers from 62 to 192 = 8255
