WHAY WOULD BE THE NEXT NUMBER IN THIS PATTERN AND WHAT RULE DOES IT FOLLOW?
4,13,40,121,

It's your turn now. What pattern do you see?
We'll be glad to check your work. 
COULD THE ANSWER BE 400

Nope.
What pattern do you see? 
I SEE 4 THEN IT SEEMS LIKE THEY ADDED A 0 TO THE NEXT 4TO MAKE 40 SO MAYBE IF I ADD ANOTHER 0 IT WOULD BE 400

Here's the pattern I see 
(4 * 3) + 1 = 13
(13 * 3) + 1 = 40
Continue this pattern. 
THE ANSWER IS 364

Yay! You've got it!! :)
