Is 3 an even natural number?
No.
Is 2 a even number?
Yes, as -2 divided by 2 results in a natural number.
What is the 69th even natural number?
Look at the series of even natural numbers: 2, 4, 6, 8, 10, 12 ... Now the positions of these numbers are: 1, 2, 3, 4, 5, 6.. If you match the position with corresponding natural number (eg. 1 with 2, 2 with 4 and so on) it looks like the corresponding Natural number is twice as the position number. The answer is: 69 x 2 = 138
Why do you get an even number when you add two even numbers?
An even number is always some quantity of 'twos' (2's), and any quantity of twos is an even number. The first even number is a quantity of twos, and the second even number is another quantity of twos. When you add the first quantity of twos to the second quantity of twos, you get a new quantity of twos. Since the new quantity of twos is a quantity of twos, it's an even number.
What is the sum of all the even numbers from 2 through 200?
To find the sum of all even numbers from 2 through 200, we can use the formula for the sum of an arithmetic series. Since the sequence is an arithmetic sequence with a common difference of 2, we can calculate the number of terms using the formula ((last term - first term) / common difference) + 1. In this case, the first term is 2, the last term is 200, and the common difference is 2. Plugging these values into the formula gives us ((200 - 2) / 2) + 1 = 100. The sum of an arithmetic series is given by the formula n/2 * (first term + last term), so the sum of all even numbers from 2 through 200 is 100/2 * (2 + 200) = 10100.
