Answer:
987.
Step-by-step explanation:
The terms in a Fibonacci series are obtained form the sum of the previous 2 terms. So the next number F(16) = 377 + 610 = 987.
4/3 is not a valid fraction for this type of problem so I am going to assume that it is 3/4. If this is a case she will need 1 and 1/4 more cups of sugar.
