14/9 ?(Reasoning: Increase denominators by 2, numerator is avg. of 11 and 17)
15/9Congrats for the great blog!
13/9 is one of the correct answers, i believe. Logic: denote the sequence this way: 3/1, 5/3, 7/5, 11/7, 13/9, 17/11,....numeritors are increasing prime numbers. denomenators are increasing odd numbers.
