# Pattern Spotting

**Missing number will be 6
The middle number is the average of the remaining number in the row.**

**In the first row, **

**middle number = (4 + 2)/2 = 3**

**In the second row, **

**middle number = (5 + 3 + 1 + 1)/2 = 5**

**In the third row, **

**middle number = (6 + 1 + 2+ 3 + 3 + 1)2 = 8 **

**In the fourth row, **

**middle number = ( 7 + 2 + 4 + 3)/2 = 8**

**In the fifth row, **

**middle number = ( 9 + 3)/2 = 6**

**Therefore, middle number is 6**
