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.
