3, 12, 48 are the first three terms of the geometric sequence. What is the number of factors of 4 that is in the 15th term?
The first term,
The fifteenth term's factorization will contain 14 fours.
The given sequence is geometric, with the common ratio being 4 and the first term being 3.
Note that the first term has 0 factors of four. The second term has one factor of four, as it is
Can you see a pattern here? The
There is also another reason for this. The nth term of a G.P is
