Answer:
The explicit formula

The recursive formula
for 
if 
Step-by-step explanation:
If a sequence is arithmetical then the difference between any of its consecutive terms will be constant
3, 3.25, 3.5, 3.75,

The difference between the consecutive terms remains constant so the sequence is arithmetic.
The explicit formula for an arithmetic sequence is:

Where d is the constant difference between the terms.

is the first term of the sequence.

So

Finally, the recursive formula is:

Answer:
NO IT WOULD BE 0
Step-by-step explanation:
Answer:
A)
Blue: 
Red: 
B)
Blue: 
Red: 
C)
No the experimental probabilities found in "A" are not equal to the probabilities found in "B". The sample size of the the experiment was not large enough to reflect the actual probability.
D)
Blue: 80
Yellow: 50
Red: 40
Orange: 30
the greatest common factor (GCF) of 12, 24, and 48 is 12.
1,000 = 10^3 (3 because there are 3 digits after the first one)
2,000 = 2 * 10^3
