Explanation.....

1.....2² – 3

32....6² – 4

139...12² – 5

394...20² – 6

893...30² – 7

1756...42² – 8

The difference between 2 and 6 is 4....6 and 12 is 6....12 and 20 is 8....20 and 30 is 10....30 and 42 is 12.....

In the same the next three numbers will be

56(42 + 14), 72(56 + 16) and 90(72 + 18)....So the three terms will be.....

3127...56² – 9

5174...72² – 10

8089....90²– 11.....
