Question 444655
Six consecutive even integers could be a, b, c, d, e, and f.  But that would be a nightmare.
Instead, let's go with:
x
x+2
x+4
x+6
x+8
x+10
.
We're told they total 450.
.
6x + 30 = 450
6x = 420
x = 70
.
That means the six consecutive even integers are:
70
72
74
76
78
80
.
Adding them, you'll find they = 450.
.
Done.
