We need to first evaluate   [ 1 + sqrt (5) ] / 2

 

This equals ≈  1.618

 

Note that the first can't be correct .....  6/6  = 1

 

Look at the second .....7/5  =  1.4

 

Look at the third .....7.5 / 4.5   = 1.66

 

And the last.....7.75 /4.25  = 1.82

 

So.....which is closest to     1.618  ????
