please help, find four consecutive integers whose sum is -2
You can actually set this up as an equation, it's just a bit tricky. So what you know about four consecutive integers is that each integer is one more than the next.
So (x) + (x+1) + (x+2) + (x+3) = -2
Can you solve it from there?
x would be the first integer, and then you know the rest.
im a little confuse so u have to add all the x together right?
Yes, when the problem says to find four consecutive integers that add to get -2, that's what they mean. You know because they are "consecutive", that given a firs integer "x", that the rest follow that pattern - each next integer is 1 greater than the last.
(x) + (x+1) + (x+2) + (x+3) = -2 (adding the consecutive integers gets -2) 4x + 6 = -2
So what do you get for x?
(the first of the four consecutive integers)
would it be 4x=-8 then u have to divide 8 with 4 right?
correct, well, divide -8 by 4 =)
