To Find:

• What comes at the place of ?

Solution:

Notice the  logic in each column

Step 1:

First column

2 Multiplied by first element added to second element gives 3rd element

2 x 5 + 11  = 21

Step 2:

Second column

2 Multiplied by first element added to second element gives 3rd element

2 x 8 + 17 = 33

Step 3:

Third column , Using same logic

2 Multiplied by first element added to second element  

2 x 7 + 15 = ?

29 = ?

Hence 29 comes at the place of ?
