What is wrong with this "proof"? "Theorem" For every positive integer n,n i =1 i = (n + 1 2 ) 2 /2. Basis Step: The formula is t
creativ13 [48]

Answer:

The basis step is not even true.

Step-by-step explanation:

The basis step would be for     n = 1.

If the basis step was true then you would have that.

\sum\limits_{i=1}^{1} i  =  \frac{(1+1/2)^2}{2}

Now. When you say

                                            \sum\limits_{i=1}^{1}  i            

That's just a fancy way of writing    1.  

On the other hand    

\frac{(1+1/2)^2}{2}  = \frac{9}{4} = 2.25

Therefore  

  1 \neq 2.25

And the basis hypothesis is false.
