x= 8
x+2 = 10
x+4=12
x+6 =14
let integer = y
then y + (y + 1) = 91
so 2y = 90
so y = 45
45 and 46 work

Answer 1:
x = 8
'x' represents 8
'x + 2' represents 10
'x + 4' represents 12
'x + 6' represents 14
Answer 2:
Let the integers be 'x' and 'x+1'
x + x + 1 = 91
2x + 1 = 91
2x = 91-1
2x = 90
x = 90/2
x = 45
The integers are 45 and 46

8, 10, 12, 14
x+ x+ 1 = 91
2x + 1 = 91
2x = 91 - 1
2x = 90
x = 90/2
x = 45
second integer is x + 1 = 45 + 1 = 46.
45 + 46 = 91.

x=8
8+2=10
8+4=12
8+6=14
Let n=integer
n+n+1=91
-1 -1
2y=90
y=45
45+1=46
45,46
