<span>The arithmetic sequences have a constant difference between two terms. This sequence does not match this criterion, look: 12-8 = 4; 8-5=3; 5-3=2. Then it is not arithmetic. Let's examine whether it is geometric. Geometric sequences have a constant ration between adjacent terms: given that 3/2 is different to 5/3, and both are different to 8/5 and so on, this sequence does not either match this requirement. Then the sequence is not arithmetic or geometric.</span>
Answer:
18 Minutes
Step-by-step explanation:
Simon and sophie each do a fraction of the job per minute like this:
-Simon does 
per minute (if we multiply this by 30 we have the completed job)
-Sophie does 
of the job per minute (again if we multiply this by 45 we have the completed job)
We will add this two to know how much of the job they do together in a minute:
They will do 
of the job per minute.
So the total time will be when they do 
, we can put this in one equation like this:
where x is the total times we need to do of the job to complete it. We solve for x:
Answer:The mean increases but the median stays the same.
Step-by-step explanation:
201 + 233 + 237 +255 +269+277+306 mean is 257 and median is 255
225 +233 + 237 +255 +269+277+306 mean is 260 and median is 255
Answer: WELL WE GO BY 150 METERS AND THAT ADDS TO TIME BUT BUT GOING TWICE YOU GET 150 METER IN ALL
