What is the pattern between these numbers?

Hey ya'll, I've tried everything i could think of to find the pattern in these numbers....Please help. I need to find the pattern in order to find the next two numbers. Here are the numbers:


3, -6, 18, -72, 360





If you have any Idea what the pattern is it would help me a lot.


Thank you!!What is the pattern between these numbers?
Hi there buddy.Its very easy.How come u couldn't solve urself.Well,it goes this way:


The first number(here 3)is multiplied by 2 which gives u 6


Then the second number is multiplied by 3 which results 18


The 3rd is multiplied by 4 which gives u 72


Numbers are positive and the next one is negative.What is the pattern between these numbers?
take the number and multiply by the negative of the ';INDEX';


(to find the second #, multiply by (-2)





3 * (-2) = -6


-6 * (-3) = 18


18 * (-4) = -72


-72 * (-5) = 360





360 * (-6) = -2,160


-2160 * (-7) = 15,120
3*-2=-6


-6*-3=18


18*-4=-72


-72*-5=360


So you always multiply by -(n+1) for the nth term


next two terms are:


360*-6=-2160 and -2160*-7=15210
3, -6, 18, -72, 360





=%26gt; 3, 3*(-2), (-6)*(-3), (18)*(-4), (-72)*(-5)





so next two numbers are 360*(-6) = -2160 and





-2160*(-7) = 15120
Multiply by -2, then -3, then -4, then -5. Multiply by -6.





-2160. Then -7.





15210.
