Best ResponseYou've already chosen the best response.0it's an easy proof....but it's still nice to see some professional do it

Best ResponseYou've already chosen the best response.0i wrote that formula wrong...

Best ResponseYou've already chosen the best response.2See \[\S_n = \cfrac{n}{2} (2a + (n1)d)\]

Best ResponseYou've already chosen the best response.2Now put 2a +(n1)d = a + a+(n1)d = a_1 + a_n

Best ResponseYou've already chosen the best response.2You get ur answer !

Best ResponseYou've already chosen the best response.0i don't think that proves anything...that was formula transformation

vishweshshrimali5

Best ResponseYou've already chosen the best response.2see a_n = a+(n1)d

Best ResponseYou've already chosen the best response.2That really does //////////// :)

Best ResponseYou've already chosen the best response.2You don't want to use the first formula ?

Best ResponseYou've already chosen the best response.0can you prove a_n = a + (n1)d?

Best ResponseYou've already chosen the best response.0i think you;re confused....this is proving...not substitution

Best ResponseYou've already chosen the best response.1suppose we have 1,2,3,4.....100 adding all, we can see it like this (1+100) + (2+99) .... ( 50 + 51) => (101)*50 = (1 + 100) * (100/2) you may generalize this..

Best ResponseYou've already chosen the best response.2And u asked for a proof ;)

lgbasallote

Best ResponseYou've already chosen the best response.0that wasn't a proof @vishweshshrimali5 ....it was formula transformation

lgbasallote

Best ResponseYou've already chosen the best response.0and substitution isn't proving either.... @shubhamsrg

Best ResponseYou've already chosen the best response.2Whatever........... leave it I can prove that without using a_n formula

vishweshshrimali5

Best ResponseYou've already chosen the best response.2But you will have to accept that a_n = a+(n1)d That is basic def. of AP

Best ResponseYou've already chosen the best response.2I am also surprised @shubhamsrg O.o

Best ResponseYou've already chosen the best response.0are any of you familiar with mathematical induction?

vishweshshrimali5

Best ResponseYou've already chosen the best response.2You want that proof........

lgbasallote

Best ResponseYou've already chosen the best response.0what both of you did was substitution (which is NEVER accepted as proofs)

Best ResponseYou've already chosen the best response.2Let P(n) be the given statement

lgbasallote

Best ResponseYou've already chosen the best response.0no. i want other proof

lgbasallote

Best ResponseYou've already chosen the best response.0induction is too dull and boring and predictable

Best ResponseYou've already chosen the best response.1you're amazing you know that ?

Best ResponseYou've already chosen the best response.2@lgbasallote please give us a "hint" of the proof u want

lgbasallote

Best ResponseYou've already chosen the best response.0actually...it's surprising @vishweshshrimali5 does know induction...

lgbasallote

Best ResponseYou've already chosen the best response.0any proof as long as it's valid and not induction

Best ResponseYou've already chosen the best response.1induction is one of the many great tools we have in mathematics today!

Best ResponseYou've already chosen the best response.0preferrably, i like to see direct proof and contradiction

lgbasallote

Best ResponseYou've already chosen the best response.0i like deduction much more

vishweshshrimali5

Best ResponseYou've already chosen the best response.2Ok lets try u want to deduce a formula from a continuous pattern

Best ResponseYou've already chosen the best response.0time for the site to go down....
