Answer:

2. Check your work

3. Correct

Explanation:

2. The equation tells you ...


a_2=2a_1+4=2(-1)+4=-2+4=2

Only one answer choice has +2 as the second term of the sequence. The one you selected is not it.

__

3. The expression can be simplified to ...


a_n=((n+3)!)/(n+3)=(n+2)!

Filling in n=1 tells you all you need to know:


a_1=(1+2)!=3\cdot 2\cdot 1=6

The answer you selected has a first term of 6, so your choice is correct.
