What is the sum of even numbers from 1 to 5550? Here we will show you step-by-step how to calculate the sum of even numbers from 1 to 5550.
Step 1) We start by finding the first (F) and last (L) even numbers from 1 to 5550. It is easy to do that by simply looking at the numbers. The first even number is 2, and the last even number is 5550.
F = 2
L = 5550
Step 2) Next, we calculate the total even numbers (T) there are from 1 to 5550, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (5550 - 2 + 2) ÷ 2
T = 5550 ÷ 2
T = 2775
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 5550, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (2775 ÷ 2) × (2 × 2 + (2 × (2775 - 1))
Sum = 1387.5 × (4 + 5548)
Sum = 1387.5 × 5552
Sum = 7703400
Sum of even numbers from 1 to 5550 = 7703400
