No.
Yes, as -2 divided by 2 results in a 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

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.
In normal arithmetic, never.
Find the sum of the first hundred even natural number divisible by 5?
A set is a set and does not need an arithmetic operation.
It can, for example, in base 7 arithmetic.
YES. Any even natural number is a multiple of 2.
It can be any number. Two numbers do not even determine whether the "sequence" is arithmetic, geometric or other.
You take the arithmetic mean of the middle two numbers.
No.
114 The equation is 50x + summation (2(n-1) = 3250 where n = 1 to 50 and x is first even number
even, whole, non-negative numbers. (zero is not a natural number)
Yes, that is correct.
