Answer:
aₙ = 4(5)ⁿ⁻¹
Explanation:
To identify a geometric series: second term = √(first term * third term)
Here given:
check ============
20 = √(100*4)
20 = √400
20 = 20 Hence its a geometric term.
Find common difference (r):
20/4 = <u>5</u> or 100/20 = <u>5</u>
Geometric term formula:
aₙ = a₁(r)ⁿ⁻¹ [where a1 is the 1st term, r is common difference]
<u>insert values found</u>
aₙ = 4(5)ⁿ⁻¹ ......this is the nth term.

Answer:
Step-by-step explanation:
GIVEN: A bag contain red marbles, green marbles and blue marble. A marble is chosen at random from the bag and not replaced, then a second marble is chose.
TO FIND: What is the probability both marbles are green.
SOLUTION:
Total marbles in bag
total number of green marbles
Probability that first marble will be green
Probability that second marble will be green
As both events are disjoint
probability both marbles are green
Hence the probability both marbles are green is

Add all prices together and then when you get the answer multiply it by 4 and you will get $215.19</span>
