Interesting Maths Riddle for genius !!!!?

Question

In war in two countries, let 3 left from one and 1 from enemy.they decide to comit suicide. Sr. 1 is Captain and they die at alternate places. 1 dies first, then 3 ,2 and 4 left at the end. (always 1 dies first) In this case to survive you should be at sr.4. If there are 'n' people where should you stand to survive?

Answer 1

The pattern is as follows:
f(2) = 2
f(3) = 2
f(4) = 4
f(5) = 2
f(6) = 4
f(7) = 6
f(8) = 8
f(9) = 2
f(10) = 4
f(11) = 6
f(12) = 8
f(13) = 10
f(14) = 12
f(15) = 14
f(16) = 16
f(17) = 2
...

Basically, you have 1 even number, then 2 even numbers, then 4 even numbers, then 8 even numbers, etc.

f(n)=2*floor( n + 1 - 2^floor( log(n+1) / log(2) ))

Answer 2

even as i became a sturdy bit youthful, I did. I save in recommendations status in a save even as i became 12 or so and only freezing in position, being beaten by the passage of time. quite understanding that the particular second... hell, 2d, i became experiencing might want to in no way ensue back. existence is fleeting. once you die... properly, no man or woman is responsive to. i actually am egnostic.

We, as people, are fearful of the unknown... issues we are able to not come across. Religions talk of religion... faith is an unquestioning SURENESS of a few thing, with none reality behind it. I actually have a difficulty with this, as you would possibly want to to boot. i think you. it truly is scary, overwhelming, and can want to be type of... properly, devastating. the in reality suggestion i visit grant you with is to push those recommendations down. Do some thing that distracts you and also you delight in and keep in mind that each and each second might want to properly be everyone's very last. tell human beings you adore them, chuckle lots, take disadvantages, drop your inhibitions, don't be fearful of issues, because in the great, this one existence is all you acquire.
