240, 120, 60, 30, ……
In the sequence above, each term after the first is ½ of the preceding term. What is the least term of the sequence that is greater than 1?
32/15
16/15
15/8
15/4
15/2
Kindly explain your reasoning. I am looking for multiple ways to solve this problem.
Thanks,

next term = 30/2= 15
next term = 15/2
next term = 15/4
next term = 15/8
next term = 15/16, at this point you should stop, we need a value greater than 1, clearly 15/16 cannot be greater than 1
hence answer is 15/8.
Hope this helps.
