So have the sequence: 
To check if the sequence is geometric, we are going to find its common ratio; to do it we are going to use the formula:
where
is the common ratio
is the current term in the sequence
is the previous term in the sequence
In other words we are going to divide the current term by the previous term a few times, and we will to check if that ratio is the same:
For

As you can see, we have a common ratio!
We can conclude that our sequence is a geometric sequence and its common ratio is

The number of hours that should be used to study over the weekend =hrs
The number of hours to study 3 credit course is = 6hrs/ week.
The number of hours studied on monday, wednesday and friday,
= 3/5 + 16/4 +2/3
The lowest common multiple of the denominators 5, 4 and 3 = 60
=
= 316/60
Reduce to the lowest figure by dividing through with 4,
= 79/15
To detemine the extra hours to be studied over the weekend, subtract 79/15 from 6.
that is, 6/1 - 79/15
The lowest common multiple of denominators 1 and 15 = 15
=
= hrs
