(For example, we flip a coin and want heads, but it can land on heads or tails. Our probability of getting heads is 1/2, one way to get heads over the 2 possible outcomes)

So for this problem, there's 20 possible things that CAN happen (3 + 7 + 10) and 10 ways we get what we want (a green marble).

Our probability of getting a green marble is $\frac{10}{20\\}$ , which simplifies to $\frac{1}{2}$

Answer:

an = 4n +5

Step-by-step explanation:

First we need to find a common difference

d = a2-a1 = 13-9 = 4

The formula for an

an =a1+d(n-1)

an = 9 + 4(n-1)

Distributing

an = 9+4n-4

Combine like terms

an = 4n +5
