Answer:
B is Geometric and its next terms are 81, 243, 729...
See example below to complete other problems.
Step-by-step explanation:
Geometric sequences have a pattern that is exponential. Because of this, they do not have a constant rate of change using addition or subtraction. Instead, they have a constant rate through multiplication and division called a common ratio. Problem B is geometric because as you subtract each y value you get a different value each time. It is not a common difference. But if you divide, you find a common ratio.
Example: 27-9= 18 27/9 = 3
9-3 = 6 9/3 = 3
etc. Common ratio of 3
Answer:
9
Step-by-step explanation:
That's <u>always</u> true if <em>either</em> the exponent <em>or </em>the base is less than ' 1 '.
(But not always of they both are.)
Answer:
(7+5)*6+3=75
Step-by-step explanation:
You could just i mean try different ways in order to find the answer. I just tried multiple ways until i got this though (sorry if it is disappointing :( I just did it)
The * means multiply
