2,10,30,68,130,?

• 1^3 + 1
  2^3 + 2
  3^3 + 3
  4^3 + 4
  so ans is 6^3 + 6

• Ans: 222
  
  2^3=8+2=10
  3^3=27+3=30
  4^3=64+4=68
  5^3=125+5=130
  6^3=216+6=222

• 10-2=8
  30-10=20
  68-30=38
  130-68=62
  now for the series 8,20,38,62
  20-8=12
  38-20=18
  62-38=24
  so for last case
  6 is added to each number.
  next term for the second series generated from the first one is 62+(24+6)=92
  so the last term is 130+92=212

• 1^3 + 1
  2^3 + 2
  3^3 + 3
  4^3 + 4
  so ans is 6^3 + 6

• It's a pyramid type problem..... See the Difference that is 8,20,38,62 then consider diff between these we get 12, 18,24 then we get pattern i.e..+6 next obviously 30 then 62+30=90 at last 130+92=222

• 2,10,30,68,130
  10-2=8
  30-10=20
  68-30=38
  130-68=62
  20-8=12
  38-20=18
  62-38=24
  Similarly 24+6 = 30
  62+30=92
  130+92=222
  So ans is 222
