g)14
h)none

• 50 is the odd man.. diff between sucessive no.s is a perfect square

• b.50
  
  diff b/w consecutive nos. are squares
• 15 years agoHelpfull: Yes(2) No(0)
• 50
• 15 years agoHelpfull: Yes(1) No(0)

• 15 years agoHelpfull: Yes(0) No(2)
• diff between successive nummbers is squares
• 10 years agoHelpfull: Yes(0) No(0)
• 1=0^2+1^2
  5=0^2+1^2+2^2
  14=0^2+1^2+2^2+3^2
  30=0^2+1^2+2^2+3^2+4^2
  55=0^2+1^2+2^2+3^2+4^2+5^2
  91=0^2+1^2+2^2+3^2+4^2+5^2+6^2
