Consecutive integers are numbers in a row on a number line (ie. 4,5,6 or 457,458,459 or 12341, 12342, 12343). They can also be negative as long as the problem doesn't specify if it's positive.
x= first integer
x+1= second integer
x+2= third integer
x+3= fourth integer
Add the four integers equal to 354.
x + (x+1) + (x+2) + (x+3)= 354
combine like terms
4x + 6= 354
subtract 6 from both sides
4x= 348
divide both sides by 4
x= 87 first integer
THREE REMAINING INTEGERS
x+1= 87 + 1= 88 second integer
x+2= 87 + 2= 89 third integer
x+3= 87 + 3= 90 fourth integer
ANSWER: The four consecutive integers are 87, 88, 89 and 90.
Hope this helps! :)
