In a geometric sequence each number after the first is found by multiplying the previous number by a fixed number called the common ratio.
In an arithmetic sequence, each term is equal to the previous term plus or minus a constant called the common difference.
In your problem we have a sequence of numbers that appears to be decreasing in value, but on the surface it doesn't appear to be by any constant number... but if you look closely, the denominator 34 is exactly twice the other denominator 17. This would lead me to look at a common denominator to see if anything takes shape...
9/17 = 18/34
15/34
6/17 = 12/34
9/34
Now we see that each number is the previous number minus 3/34, so we have a common difference of 3/34.
This would match the definition of an arithmetic sequence and NOT a geometric sequence.
Answer:
the answer is 11/21 or 0.523809524

Step-by-step explanation:
Twice means times 2.
1) 2(ab) gives twice the product of a and b.
2) (2a)b gives the product of twice a and b.
Answer:
10:30am
Step-by-step explanation:
total lesson time is 1 hr and 15 min (10 to 11:15).
lesson time is 1 hr total and the break mid way is :15 long.
the lesson before the break is from 10-10:30 (:30 length)
break is at 10:30 (:15 long concluding at 10:45).
lesson resumes at 10:45 when break is over
the lesson runs another :30 until 11:15 (10:45-11:15)
halfway thru the lesson is 10:30am for the break to start
