7, 9, 11,

generalize the pattern by finding an explicit formula for the nth term.

an = 5 + 2n

Step-by-step explanation:

Each time it increases by the same amount (2), so this is an arithmetic sequence:

an = a₁ + d (n - 1)

Given a₁ = 7 and d = 2:

an = 7 + 2 (n - 1)

an = 7 + 2n - 2

an = 5 + 2n

Check our

n=1: a₁ = 5 + 2(1) = 7

n=2: a₂ = 5 + 2(2) = 9

n=3: a₃ = 5 + 2(3) = 11

n=4: a₄ = 5 + 2(4) = 13

answer is x<

answer: a. 13/44

step-by-step explanation: judging by the information given to us, we are looking for experimental probability. we can see that 13 males have chosen chocolate ice cream. there are 44 ice creams in total (remember that the total is always the denominator). so our answer is 13/44.
