You can add a answer block which increments the answer counter.
\defineblock[question]
\defineblock[answer]
\defineenumeration[question][text={Question}]
\defineenumeration[answer] [text={Answer}]
\keepblocks[question]
\hideblocks[answer]
\starttext
\chapter{Question}
\beginquestion
\startquestion
Question 1.
\stopquestion
\endquestion
\beginanswer
\startanswer
Answer 1.
\stopanswer
\endanswer
\beginquestion
\startquestion
Question 2.
\stopquestion
\endquestion
\beginanswer
\incrementcounter[answer]
\endanswer
\beginquestion
\startquestion
Question 3.
\stopquestion
\endquestion
\beginanswer
\startanswer
