What is the 7th term in the sequence below?
3,12,48,

Every term is four times the last.  Using this, we see that:

5th term: 192*4=768
6th term: 768*4=3072
7th term: 3072*4=12288

Note that technically, we're making an educated guess that this is the method the sequence is generated.  Just having four terms is not enough to PROVE that this is the case, but multiplying by four is by far the most likely sequence.

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance
