Zina spends 15 hours setting up her sewing machine and making one hat. The total amount of time spent making hats can be represented by the sequence below1.5, 2.25, 30,3.75. . .Which recursive formula can be used to determine the total amount of time spent making hats based on the total amount of time spent previously?(1) f(n + 1) = f(n) + 1.5(2) f(n + 1) = f(n) + 0.75(3) f(n+ 1) = 1/2f(n)(4) f(n + 1) = 3/2f(n)
