Let the unknown number be X:
3x-800 = 1200
Move -800 to the other side of the equation changing the - sign to a + sign:
3x = 1200+800
3x = 2000
Divide both sides of the equation by 3 to find the value of x:
x = 666 and 2/3 or 666.666.........recurring decimal
One number is 63 and the other is 21.
Their sum is three times the middle number.
Each number is three times the previous number.
12 and 28
Even numbers. A geometric progression where each number is three times the previous number.
The numbers are 21 and 63.
One number is 63 and the other is 21.
Since one number is 3 times the other, I'd divide 84 by 4 and get 21. This is the lower number so the other must be 63.
