113 , 135 , 3511 , 51121, _ , _ ,.......................


Answer
 
Tn =  Last two numbers (Tn-1)  [ (2 * First number(Tn)+Second number (Tn)]
113 , 135 , 3511 , 51121, _ , _ ,.......................
1 1 3 ,  1 3 ((1 * 2) +3) , 3511, 51121, _ , _ ,.......................
113 ,  1 3 5 , 3 5 ((2 * 3)+5), 51121, _ , _ ,.......................

Next two numbers   11 21 (11 *2)+21 = 112143
                            21 43 (21 *2)+43 = 214385

113 , 135 , 3511 , 51121, 112143, 214385 ,.......................
