What is the sum of even numbers from 1 to 6497? Here we will show you step-by-step how to calculate the sum of even numbers from 1 to 6497.
Step 1) We start by finding the first (F) and last (L) even numbers from 1 to 6497. It is easy to do that by simply looking at the numbers. The first even number is 2, and the last even number is 6496.
F = 2
L = 6496
Step 2) Next, we calculate the total even numbers (T) there are from 1 to 6497, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (6496 - 2 + 2) ÷ 2
T = 6496 ÷ 2
T = 3248
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of even numbers from 1 to 6497, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (3248 ÷ 2) × (2 × 2 + (2 × (3248 - 1))
Sum = 1624 × (4 + 6494)
Sum = 1624 × 6498
Sum = 10552752
Sum of even numbers from 1 to 6497 = 10552752
