53
Explanation below:
Consecutive numbers means that the next number is 1 larger. This can be represented by x (the first number) + 1, x + 2, x + 3 . . .
So, for this problem the equation would looks like:
x + (x + 1) + (x + 2) + (x + 3) + (x + 4) = 270
Now combine the like terms to get:
5x + 10 = 270 (Solve for x, subtract 10 from both sides)
5x = 260 (Divide both sides by 5)
x = 52
That means the first number of the sequence is 52. The following numbers are 53, 54, 55, 56.
The second number is 53.
Hope that helps!
