• half of a number squared is equal to two times the number
  
  (n(1/2))^2 = 2n
  n^2 = 8n
  n^2-8n=0
  
  n=0 or n=8

• let the number be x.
  then according to given condition:-
  (x/2)^2=2x
  thus, x=8

• If number is x, then
  
  (x/2)^2=2x
  (x^2)/4=2x
  (x^2)/x =8
  x=8
  
  8 is the desired number.
