These are the difference of the numbers in above series.
So, the first one should be 30.
And how did you get 2742?

516,1002

so now,

1740+991=2731

so

2731+2742=5473

Ans is 6121.
31-1 = 30 = (3)^3 +3
253-31 = 222 = (6)^3 + 6
991 -253 = 738 = (9)^3 + 9
2731 - 991 =1740 =(12)^3 + 12
so te ans will be 2731 + (15)^3 + 15 =6121
