The first four terms of a sequence are shown below.
8, 5, 2, -1
which of the following functions best defines this sequence?
f(1) = 8, f(n + 1) = f(n) + 3, for n greater than 1
f(1) = 8, f(n + 1) = f(n) -5; for n greater than 1
f(1) = 8, f(n + 1) = f(n) + 5; for n greater than 1
f(1) = 8, f(n + 1) = f(n) - 3; for n greater than 1

Adoctor administers a drug to a 38-kg patient, using a dosage formula of 50 mg/kg/day. assume that the drug is available in a 100 mg per 5 ml suspension or in 500 mg tablets. a. how many tablets should a 38-kg patient take every four hours? b. the suspension with a drop factor of 10 ggt/ml delivers the drug intravenously to the patient over a twelve-hour period. what flow rate should be used in units of ggt/hr? a. the patient should take nothing pills every four hours. (type an integer or decimal rounded to the nearest hundredth as needed.)

Can someone factor this fully? my friend and i have two different answers and i would like to know if either of them is right. you in advance. a^2 - b^2 + 25 + 10a
