Find four consecutive intergers such that twice the second is equal to the fourth.

Consecutive integers are numbers that are right next to each other on the number line with no whole numbers in between them. For example:

7, 8, 9, 10 are consecutive integers

3, 5, 8, 11 are not

So you need to find a sequence of consecutive integers where the second number multiplied by two is equal to the forth.

Spoiler Alert:

There is one one sequence that comes to mind. "1, 2, 3, 4", As 2 is the second number, 2*2 = 4, and four is the forth number in the sequence.
