Answer:
f(n) = 2 ×
Step-by-step explanation:
In order to write an explicit rule for a geometric function, you need to know the common ratio; you can find the common ratio by dividing two consecutive terms:
6 ÷ 2 = 3, 18 ÷ 6 = 3, 54 ÷ 18 = 3, etc..
Now you know the common ratio is 3. At this point you can write your explicit function following the rule f(n) = [1st term] × [common ratio]^(n-1):
f(n) = 2 × 3^(n-1)

Answer:
<h2>Here's what makes an integer odd:</h2>- It is NOT a multiple of 2.
- When divided by 2, the quotient would be a decimal or have a remainder or fraction.
- It is a multiple of 2.
- When divided by 2, the quotient has a whole number.
<em>The odd numbers from one to 10 are: 1, 3, 5, 7, 9.</em>
<em>The even numbers from one to 10 are: 2, 4, 6, 8, 10. </em>
- With big numbers, if it ends with any of the odd numbers from one to ten, listed above, it would be odd. This goes for the same with even.
- An odd number and even number has a pattern....
[odd, even, odd, even, odd...] [1, 2, 3, 4, 5]
- So, if x was an odd number, adding it by 2, 4, 6, etc. will result in another odd number.
Here's an example:
<em>See how x is an odd number and the sum of the number and two makes another odd number? </em>
The same can go with an even number:
<em>See how x is an even number and the sum of the number and six makes another even number? </em>
I hope my answer helps you understand even and odd numbers.
