Answer:
it is a triangle whose sides appear to be all different lengths
F(1) = 42
f(n) = f(n-1) - 5
f(2) = f(1) - 5
f(2) = 42-5
f(2) = 37
a1 = 42
a2 = 37
r = 5
PA: (42, 37, 32, 27, 22, 17, 12, 7)
In order to find the probability of drawing a marble that is NOT BLUE, we must find the ratio of non-blue marbles to the total amount of marbles
Let's count how many marbles total there are first
8 red + 3 blue + 1 green = 12 marbles total
Now, how many marbles are there that <u>ARE NOT BLUE </u>
8 red + 1 green = 9 marbles <u>THAT ARE NOT BLUE </u>
Now<em> let's create a ratio</em> to find a probility
9/12
This can be simplified to 3/4 by taking out the common factor of 3
Your answer is D! "three-fourths"
The numbers are 59 and 61
