Answer:

73, 74, 75

Step-by-step explanation:

So the sum of three consecutive integers is 222.

Let's let the first integer be n.

Then the second integer <em>must</em> be (n+1).

And the third integer must be (n+2).

They total 222, thus:

n+(n+1)+(n+2)=222

Combine like terms:

3n+3=222

Subtract 3 from both sides:

3n=219

Divide both sides by 3:

n=73

So, the first integer is 73.

So our sequence is 73, 74, and 75.

And we're done!
