Answer:

1 x 2 = 2

2 x 3 = 6

3 x 4 = 12

4 x 5 = 20

5 x 6 = 30

So next numbers will be as follows;

6 x 7 = 42 &

7 x 8 = 56

 

or the second logic is;

1^2 + 1 = 1 + 1 = 2

2^2 + 2 = 4 + 2 = 6

3^2 + 3 = 9 + 3 = 12

4^2 + 4 = 16 + 4 = 20

5^2 + 5 = 25 + 5 = 30

So the next numbers will be as follows;

6^2 + 6 = 36 + 6 = 42

7^2 + 7 = 49 + 7 = 56

Answer = 42, 56.
