Farmer Fred has 5 rabbits. Each month the population of rabbits increases by 3 rabbits. Write an equation that will find the number of rabbits Farmer Fred has in 1 year

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.
