Dear Student,

Please find below the solution to the asked query:

We have  : 1 , 28 , 92 , 217 , 433 , 776 , ? , So

We write our series , As :

1 + 27 =  1 + 3³ =  28 , 

28 + 64 =  28 + 4³ =  92 ,

92 + 125 =  92 + 5³ =  217 ,

217 + 216 = 217 + 6³ = 433 ,

433 + 343 = 433 + 7³ = 776 

So, Next number will be :

776 + 8³ =  776 + 512 = 1288 

So , Our series : 1 , 28 , 92 , 217 , 433 , 776 , 1288


Option ( C )                                                                ( Ans )
