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.

step-by-step explanation:

chemists are often responsible for designing a chemical reaction and analyzing the products obtained from it. one significant part of designing a chemical reaction is determining the amount of each reactant that is needed and the amount of each product that will be produced. in order to do so, chemists use stoichiometry, the quantitative relationships between reactants and products.
