Question 1142261
<br>
Actually, it is impossible to answer the question as it is presented.<br>
Although the given first four terms form a geometric sequence with common ratio 2/3, it is BAD MATHEMATICS to assume any information about a problem that is not given.<br>
Since the problem doesn't tell us that the sequence is geometric, we can't assume it is just because the first four terms make it look geometric.<br>
So the subsequent numbers in the sequence could be anything -- making it of course impossible to answer the questions....
