Use the given terms of the sequence to answer the question.

a1=10

a2=6

a3=2

a4=-2

Which recursive formula represents the sequence?

A. a1=10

an=an-1+4

B. a1=10

an=an-1-4

C. a1=10

an=an-1+10

D. a1=10

an=an-1-10

B.

Step-by-step explanation:

Each term is equal to the one before it minus 4. This is represented in "A-sub-N equals A-sub-N-minus-1 plus four," or an = an-1 + 4

"an" is the current term you're on, such as a1, a2, etc.

"a1" is where your sequence starts.

Say we want to fin a5. "an-1" in this case equals "a4" or - 2. we then take that number and subtract the 4 in the equation, resulting in a5 = - 6.

I hope this all makes sense.
