I like to rephrase math into plain English. Consecutive = in a row. Integers = whole numbers. Find 4 numbers in a row where the first two numbers = four more than the fourth number and -4 multiplied.
Name the numbers. N, N+1, N+2, and N+3. Plug them into the equation. -1(N + N+1) = -4(N+3) + 4
Add anything inside the parentheses, then use the distributive property to get rid of the parentheses.
-1(2N+1) = -4(N+3) + 4
Name the numbers. N, N+1, N+2, and N+3. Plug them into the equation. -1(N + N+1) = -4(N+3) + 4
Add anything inside the parentheses, then use the distributive property to get rid of the parentheses.
-1(2N+1) = -4(N+3) + 4
-2N - 1 = -4N - 12 + 4
Combine like terms
-2N - 1 = -4N - 8
Get all the variables on one side
-2N + 4N - 1 = -4N + 4N - 8
2N - 1 = -8
Get all the constants (regular numbers) to the other side
2N - 1 + 1 = -8 + 1
2N = -7
Get the variable by itself by "undoing" the operation. 2 is being multiplied by N. To get rid of the 2, divide by 2. Then divide by 2 on the other side.
2N/2 = -7/2
N = -3.5
Since this is not a whole number, I suspect there is information missing from the problem. Perhaps the question is looking for consecutive odd or even numbers?
