For problems like this, let n be the lowest number. Then let n+2, n+4, etc be the 'next consecutive' integers.
An example, three consecutive even integers have an average of 10, what are they?

so n+2 = 10 and n+4 = 12
8,10,12

:
"Three consecutive even integers are such that the square of the third is 76
more than the square of the second"
:
Break it down as follows:
:
Three consecutive even integers:
x, (x+2), (x+4)
:
are such that the square of the third is 76 more than the square of the second.
(x+4)^2 = (x+2)^2 + 76
FOIL
x^2 + 8x + 16 = x^2 + 4x + 4 + 76
:
Arrange the x's on the left and the numbers on the right:
x^2 - x^2 + 8x - 4x = 4 + 76 - 16
:
4x = 64
x =
x = 16 is the 1st even integers
:
Find the three integers.
16, 18, 20
:
:
Check solution in the statement:
"square of the third is 76 more than the square of the second."
20^2 = 18^2 + 76
400 = 324 + 76; confirms our solution
