What is the sum of even numbers from 51 to 52? Here we will show you step-by-step how to calculate the sum of even numbers from 51 to 52.
Step 1) We start by finding the first (F) and last (L) even numbers from 51 to 52. It is easy to do that by simply looking at the numbers. The first even number is 52, and the last even number is 52.
F = 52
L = 52
Step 2) Next, we calculate the total even numbers (T) there are from 51 to 52, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (52 - 52 + 2) ÷ 2
T = 2 ÷ 2
T = 1
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of even numbers from 51 to 52, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (1 ÷ 2) × (2 × 52 + (2 × (1 - 1))
Sum = 0.5 × (104 + 0)
Sum = 0.5 × 104
Sum = 52
Sum of even numbers from 51 to 52 = 52
