What is the sum of the first 20 even natural numbers?

The correct answer is: 220

The sum of the first 20 even natural numbers can be found by adding up each of the numbers individually. It is not necessary to find the average and then multiply by the total number of numbers. Options A, B, and C suggest using this method, which is incorrect. Option A is the sum of the first 10 even natural numbers, option B is the average of the first 20 even natural numbers multiplied by 20, and option C is the sum of the first 11 even natural numbers. These methods do not account for all 20 numbers, thus they are incorrect. Only option D correctly adds up all 20 even natural numbers to find the sum.
