-
- 1^3 + 1
2^3 + 2
3^3 + 3
4^3 + 4
so ans is 6^3 + 6 - 11 years agoHelpfull: Yes(62) No(0)
- 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 - 11 years agoHelpfull: Yes(12) No(3)
- 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 - 11 years agoHelpfull: Yes(3) No(8)
- 1^3 + 1
2^3 + 2
3^3 + 3
4^3 + 4
so ans is 6^3 + 6 - 11 years agoHelpfull: Yes(3) No(0)
- 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 - 6 years agoHelpfull: Yes(0) No(0)
