SOLUTION: How many different sequences of the form <b>ccvcv</b> are there where <b>c</b> represents one of the 21 consonants and <b>v</b> represents one of the 5 vowels in the English alphab

Question 1109789: How many different sequences of the form ccvcv are there where c represents one of the 21 consonants and v represents one of the 5 vowels in the English alphabet? Assume no letter can be repeated in the same word.
-----------
Since the sequence needs to be ccvcv I assume that this requires a permutation (order matters).
I was thinking about (21*20*19)+(5*4)...but I don't feel like this is the right way to go.
Thanks in advance for your help!

What's wrong with your expression is that there is no plus sign.  
It's "times" all the way:

21*20*19*5*4 = 159,600
