Can you please solve this from yesterday? http://web2.0calc.com/questions/ready-for-more-h-l

 

And...

 

Find the two different equations to assume the amount of blocks there are in each stage. (See other ones for instruction)

                                                                      ()

                                        ()                           ()

     ()                              ()()()                    ()()()()()

                                        ()                           ()

                                                                     ()

Here's one answer :

 

1^2 = 1

2^2  = 4

3^2  = 9

 

so

 

s^2   = n

 

Here's another using summation notation :

 

1 = 1

1 + 3  = 4

1 + 3 + 5  = 9

 

so

 

Σ  [2s - 1]      =   1 + 3 + 5 + 7 + ..............

s=1

 

 

 

cool cool cool
