Answer:
Step-by-step explanation:
Since there's no one one number you can add to one number in the sequence to get to the next number, this is not arithmetic. It must be geometric. We need then to find the common ratio. Let's start with the first 2 numbers, find a ratio, and then use it to test for accuracy.
10x = 15 and
x = 
If this is in fact a geometric sequence witha common ratio of 3/2, we should be able to multiply 15 by 3/2 to get to the next number in the sequence. Let's try it out:
Good. So the common ratio is 3/2. The formula for an explicit geometric formula is
where a1 is the first number in the sequence and r is the common ratio. Filling in:
Answer:
I think it would be x÷6-9 or x/6-9
Step-by-step explanation:
Quotient means to divide so you are dividing x by 6. Decreased by 9 means subtract by 9. I hope this helps you! :)
15 multiplied by 13 is equal to 195.
The answer is
200%Why? --- A change from 12 to 36 represents a positive change (increase) of 200%
Use the formula found below on this webpage to find the percent change by replacing the given values:
Percent change = [(12 - 36) / 12] x 100 = 200 % (increase)
Where: 12 is the old value and 36 is the new value. In this case we have a positive change (increase) of 200 percent because the new value is greater than the old value.
Hope this helps. :)

1.68 because you multiply then divide by 100
