The mode for this set of numbers is 18 because there are three 18's in the set of number, and only two 20's. :D

Mode is just the number that occurs most often.

<span>18, 15, 16, 18, 20, 17, 14, 17, 18, 20
</span>
17.5 and 17.3 never occur. 18 occurs 3 times. 20 occurs twice.

So 18

Rewrite 4n^2+2n as a factorial.
Shkiper50 [21]

Answer:

4n²+2n as a factorial is given as:

= (2n+1)!/(2n-1)!

Step-by-step explanation:

We are given an expression which has to be converted into factorial form.

The expression is as follows:

4n^{2} + 2n\\ = 2n(2n+1)\\ = (2n+1)2n\\

Now we know that 2n+1 and 2n differs by '1' and the next smaller term is '2n-1'.

Hence, multiplying and dividing by '(2n-1)!'; we get:

= ((2n+1)(2n)(2n-1)!)/(2n-1)!

we know that x(x-1)(x-2)! = x!, so:

= (2n+1)!/(2n-1)!
