What is the sum of even numbers from 1 to 5842? Here we will show you step-by-step how to calculate the sum of even numbers from 1 to 5842.
Step 1) We start by finding the first (F) and last (L) even numbers from 1 to 5842. It is easy to do that by simply looking at the numbers. The first even number is 2, and the last even number is 5842.
F = 2
L = 5842
Step 2) Next, we calculate the total even numbers (T) there are from 1 to 5842, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (5842 - 2 + 2) ÷ 2
T = 5842 ÷ 2
T = 2921
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 5842, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (2921 ÷ 2) × (2 × 2 + (2 × (2921 - 1))
Sum = 1460.5 × (4 + 5840)
Sum = 1460.5 × 5844
Sum = 8535162
Sum of even numbers from 1 to 5842 = 8535162
