Group of answer choices

2 is the initial term of the sequence.

2 is the common difference of the sequence.

2 is the common ratio of the sequence.

2 is the difference between the first and second terms in the sequence.

**Question 6**

Which is a recursive definition for, 2, 4, 8, ...?

Group of answer choices

*a*_{n} = 2*a*_{n-1} + 2

*a*_{n} = 2*a*_{n-1}

*a*_{n} = *a*_{n-1} + 2 and *a*_{0} = 2

*a*_{n} = 2*a*_{n-1 }and *a*_{0} = 2
