Find out the next two numbers in the series.
253 , 351 , 152 , 250 , 51,_ , _ ,.................

Answer

Tn-1 = Reverse form(Tn)  - 1
351 = Reverse(253) -1
152 = Reverse(351) -1
250 = Reverse(152) -1
51  = Reverse(250) -1

Next two numbers  
Reverse(51) -1 =14 
Reverse(14) -1 =40

253 , 351 , 152 , 250 , 51, 14 , 40,.................
