Okay I think to be able to solve this problem you have to find the common difference, i.e. what number you would add to the previous number to achieve the next number in the sequence.
OpenStudy (michele_laino):
your sequence is a arithmetic progression, with first term=4 and constant=3,
now the n-term is:
\[a _{n}=a _{1}+(n-1)*c=4+(n-1)*3=4+3n-3=3n+1=f(n)\]
