I think I regressed at math
PaperMath   51
N 21 minutes ago by K124659
I found the slip of paper a few days ago that I think I wrote when I was in kindergarten. It is just a sequence of numbers and you have to find the next number, the pattern is $1,2,5,40,1280,?$. I couldn't solve this and was wondering if any of you can find the pattern

two solutions
τρικλινο   8
N 3 hours ago by sadas123
in a book:CORE MATHS for A-LEVEL ON PAGE 41 i found the following


1st solution


$x^2-5x=0$



$ x(x-5)=0$



hence x=0 or x=5



2nd solution



$x^2-5x=0$

$x-5=0$ dividing by x



hence the solution x=0 has been lost



is the above correct?

What Are The Chances?
IbrahimNadeem   59
N 3 hours ago by sadas123
Hello, I'm curious to have honest advice on how far I can make it (by 11th-12th grade-ish);

If I have:

- Started AMC 8 study in 6th grade
- Started AMC 10 study in 7th grade
- Started practicing harder & went from 60 to around 100 on AMC 10 (on practice tests with official conditions)
- Started AMC 12 study in 8th grade
- Currently (fall of 8th grade) getting ~120 on AMC 10/12 & 7-10 while practicing AIME

At this rate, what are the chances of me making the USA(J)MO, for example, by ~11th grade?

Please be completely honest and don't hold back; This can be useful to see if I have the need to practice harder.

For two of my years going to Nationals we had three boys and one girl on the team; two of the boys were brothers, so they roomed together, and the boy and girl were randomly assigned roommates of the same sex from nearby states in the same position.

The MATHCOUNTS Nationals Roommate Search (or the MNRS for short) is an official gateway to participate in the RTX MATHCOUNTS National Competition. It is hosted annually on a website called AoPS (Commonly referred to as the Art of Problem Solving). To participate in this event, the following criteria must be met;
1) Participant(s) must have qualified for the RTX MATHCOUNTS National Competition via
1a) Earning a spot on their official state team through earning a spot in the top 4 individuals in the participant's state competition
1b) Qualifying in non-state territories or US affiliate schools, such as the District of Columbia or the State Department.
2) Participant(s) must have registered for said competition on the official MATHCOUNTS website.
The MNRS consists of searching for roommates in the form of requesting roommates in the case of
a) Being the only individual of a certain gender on your team (such as being the only female on your state team)
b) Not having a preference in a roommate and wanting to room with another person from another state/territory
Please do note that one does not have to participate in said event to participate in the RTX MATHCOUNTS National Competition.
For more information on MATHCOUNTS, go to mathcounts.org
