Evaluate the expression for the given value of the variable 2×(c2-5) for c=4

Three numbers x, y, and z are in the ratio 2: 7: 8. if 12 is subtracted from y, then three numbers form a geometric sequence (in the order x, y–12, z). find x, y, and z. there are 2 sets.

Using only odd number for numerators write two different subtraction problems that have a difference of 3/4
