What is the sum of even numbers from 165 to 196? Here we will show you step-by-step how to calculate the sum of even numbers from 165 to 196.
Step 1) We start by finding the first (F) and last (L) even numbers from 165 to 196. It is easy to do that by simply looking at the numbers. The first even number is 166, and the last even number is 196.
F = 166
L = 196
Step 2) Next, we calculate the total even numbers (T) there are from 165 to 196, using a formula. Here is the formula and the math:
T = (L - F + 2) ÷ 2
T = (196 - 166 + 2) ÷ 2
T = 32 ÷ 2
T = 16
Step 3) Finally, we use the information from Step 1 and Step 2, and another formula, to calculate the sum of even numbers from 165 to 196, like this:
Sum = (T ÷ 2) × (2 × F + (2 × (T - 1))
Sum = (16 ÷ 2) × (2 × 166 + (2 × (16 - 1))
Sum = 8 × (332 + 30)
Sum = 8 × 362
Sum = 2896
Sum of even numbers from 165 to 196 = 2896
