#

what is this formula for?

patent dune
#

formula for triangular no. ig

#

T (x) = x(x+1)/2

lament brook
#

what

#

is there consecutive series for perfect numbers?

lament brook
patent dune
#

well trianglular no. for n = n (n+1)/2

#

which is also sum of 1,2 , 3 , 4 ... n

lament brook
#

I don't understand you

thats what gee told me

lament brook
patent dune
#

anyways @charred fern

#

whats triangular no?

maiden tundra
lament brook
#

huh?

patent dune
maiden tundra
# lament brook huh?

Literally the text above the formula says "Even perfect numbers (except 6) are of the form".

lament brook
#

ok, but why this formula

#

what you use it for

maiden tundra
#

Because that's the formula for the even perfect numbers.

#

can you give me example?

maiden tundra
#

What do you mean, an example?

lament brook
#

using formula

patent dune
#

@lament brook whats the fromula for 1 + 2 + 3 + 4 ... + n ?

lament brook
#

n(n+1)/2

#

but this is not what I need ..

maiden tundra
patent dune
#

well so T (x) here is representing 1 + 2 + 3 + ...........+ x

maiden tundra
#

That's not what it says it's representing!!!

#

And that's not what the formula that's literally written there describes!

patent dune
#

theres written triangular number

maiden tundra
#

Where?

patent dune
#

now whats 1 + 2 + 3 + 4 + 5 + 6 +7

#

thats 28

#

so triangular number (x) = 1 + 2 + 3 + .... + x

maiden tundra
#

But that's not the formula for triangular numbers, though.

# maiden tundra Dude, it's not that hard. Pick a `p`.

I still don't understand. I don't understand english very well so I don't know what should I put to generate a perfect number. what I know perfect number is 2^(n-1)*(2^n - 1) but it not everything you put on it will be perfect number
