There is no conjecture about the sum of the first 30 positive even numbers. The answer can be derived and proven. A statement that has been proven is no longer a conjecture.
The sum of 30 and 54 is 84. You can find this by simply adding the two numbers together: 30 + 54 = 84.
20 +30 + 50
The first 4 square numbers are 1^2, 2^2, 3^2, and 4^2, which are 1, 4, 9, and 16, respectively. To find the sum of these numbers, you simply add them together: 1 + 4 + 9 + 16 = 30. Therefore, the sum of the first 4 square numbers is 30.
