An arithmetic sequence has a common difference of 2 and contains the value 86 at some point in the sequence. Which of the following recursive formulas could represent this sequence? Group of answer choices

an = an – 1 + 2; a1 = 1

an = an – 1 + 2; a1 = 2

an = an – 1 + 1; a1 = 2

an = an – 1 + 1; a1 = 1

B. ;

Step-by-step explanation:

According to the statement, we find that the following two conditions must be observed:

(Eq. 1)

(Eq. 2)

Since the difference between two even numbers leads to another even number. Hence, must be an even number and the correct answer is B.

step-by-step explanation:

81 seats

step-by-step explanation:

if you multiply 0.65 times 125 then you get 81.5 seats. well since you can't have half of a seat you have to round down and get 81 seats in the no children zones. that leave 44 seats outside of the no children zone.
