<span>Using the formula:
an = a1 +(n-1)d
 a1 = 9 (first term of the sequence)
d= -6 (common difference)

Substituting into the formula:
</span><span>an= a1 +(n-1)d
an <span>= 9 + (n-1)(-6)
</span>an = 9 - 6(n-1)
</span>
So the best answer is :<span>D. a_n = 9 − 6(n − 1) where n ≥ 1</span>

Ari mixed 2 1/4 cups of red grapes with 1/2 cups of green grapes. He then divided the grapes into bags with 3/4 cup of mixed gra
Oxana [17]

To start, our equation will look like this:

(2 1/4 + 1/2)/ 3/4 = b

To make it easier convert the 2 numbers inside the parentheses into improper fractions, and then multiply them by their least common denominator to add.

(9/4 + 1/2)

(18/8 + 4/8)

(22/8)/ 3/4 = b

Now, to divide 22/8 cups of grapes into bags with 3/4 cup of grapes, multiply 22/8 by 4/3.

(22/8)(4/3)=b

3 2/3 = b

So, if Ari has a bag with 2 1/4 cups of red grapes and 1/2 cup of green grapes, and he divides it into bags with 3/4 cup each, he will have about 3 full bags.
