Step-by-step explanation:
if she runs 24 laps a minute then the next minute she would of ran 48
Answer:
Step-by-step explanation:
Mean: You just add them altogether then divide the sum by how many numbers there are
Median: You put all the numbers from least to greatest then cross one off on the left and do the same on the right and repeat until there is either one or two numbers left if there are two number then you find the mean of those two numbers, but if you only have one number left then that is your answer
Mode: You find which number is the most common for enstance if there are two 3 and one 4 then 3 would be your answer because there are more 3 than 4
Range: You take the highest number and the lowest number of the set and subtract them and then you have your answer
Answer:
A) The first 4 terms of the sequences are: 
, 
, 
and 
.
B) An explicit formula for this sequence can be written as: 
C) A recursive formula for this sequence can be written as:
Step-by-step explanation:
A) You can find the firs terms of this sequence simply selecting an odd integer and summing the consecutive 3 ones:
(a.1)
B) Observe the sequence of odd numbers 1, 3, 5, 7, 9, 11, 13(...).
You can express this sequence as:
(b.1)
If you merge the expression b.1 in a.1, you obtain the explicit formula of the sequence:
(a.1)
(b.2)
(b.3)
(b.s)
C) The recursive formula has to be written considering an initial term and an N term linked with the previous term. You can see an addition of 8 between a term and the next one. So you can express each term as an addition of 8 with the previous one. Therefore, if the first term is 16:
(c.s)
