Answer:
The correct option is C) 5, 5/2
The sequence given is:
80, 40, 20, 10, _____, ______
If we look at the given numbers, it appears that every next number is obtained by dividing the previous number of 2.
Like 40 is obtained by dividing 80 by 2
Similarly:
Therefore, the complete sequence is:
80, 40, 20, 10, 5, 5/2
Hence the correct option is C) 5, 5/2
