Step-by-step explanation:
this is clearly not a linear sequence (the terms don't have the same difference).
so, it has to be a geometric sequence.
the common ratio is r.
s2 = s1 × r
16 = 64 × r
r = 16/64 = 1/4
control :
s3 = s2×r
4 = 16 × 1/4 = 4
correct.

a
Step-by-step explanation:
I fits the graph that is described
A logarithm is defined as a power to which a number must be raused to in order to get another number. For example,

This is because

So if we have

We have to determine what number must 10 be raised to in order to give 13 so we have
60 = 2 x 30
30 = 2 x 15
2 = 2
15 = 3 x 5
Prime factors = 2 x 2 x 3 x 5 = 60.
Hope this helps
