Each number in the series is being multiplied by (2 + (n-1)) where n = the term in the series 3 x 2 = 6 6 x 3 = 18 18 * 4 = 72 72 x 5 = 360
(4/9) x 72 = 4 x 8 = 32
18 x 4 = 72
((x+6)(x+8))-((X + 2)(X+4)) = 72(x^2 + 14x + 48)-(x^2 + 6x + 8) = 728x + 40 = 728x = 32x = 4check:((10)(12))-((6)(8)) = 72(120)-(48) = 72120 = 12012,10,8,6The numbers are 6, 8, 10, and 12.Here is how we find them:(n + 6)(n + 4) - (n + 2)n = 72; whence,(n2 + 10n + 24) - (n2 + 2n) = 8n + 24 = 72,8n = 48, andn = 6.So, let's try it!(12)(10) - (8)(6) = 120 - 48 = 72.It works!
1 x 72 = 72 2 x 72 = 144 3 x 72 = 216 4 x 72 = 288 5 x 72 = 360 6 x 72 = 432 7 x 72 = 504 8 x 72 = 576 9 x 72 = 648 10 x 72 = 720 11 x 72 = 792 12 x 72 = 864
72 / 4 = 18
eighteen 20 x 4 = 80 19 x 4 = 76 18 x 4 = 72
18 x 4 = 72
Yes, 4 times 18 is 72.YesYes it is... 18 x 4 = 72
4 quarts = 1 gallon 288 quarts = 72 gallons that is 72 x 4 if you were wondering.
x = x/4 + 18 4x = x + 72 3x = 72 x = 24
8 x 9 = 72 18 x 4 = 72
