The common factor of both 15 and 27 is 3.
42
The number which lies in between 6 and 27 is 16.5 which is derived by (6+27)/2.
The word increase means the problem is addition: 15 + x = 27. Reorder the problem so that it is subtraction: 27 - 15 = x and solve for x. X = 12.
41 is the prime number in this list.
The number at the midpoint of these two numbers is (15 + 27)/2 = 21
3(5-x) = 27 15 - 3x = 27 15 - 3x + 3x = 27 + 3x 15 = 27 + 3x 15 - 27 = 27 - 27 + 3x -12 = 3x -4 = x To check 3(5- -4) ? 27 15 - -12 ? 27 15 + 12 = 27
