**Only Math Master Can Spot the Missing Number**

To become a math master, you need to take every step correctly.

As you can see in the image the first number is 4, the second line of the number is 6 and 2, the third line number is 9, 3, 1 and the forth line number is 19,10, 7 and ?

This question mark is the challenge you find!

So, now start the timer!

For those who just improve their math subject level, you must see in the below answer section!

**The answer**

To solve this puzzle, we need to identify the pattern in the given numbers. Let’s analyze it row by row:

1st row: 4

2nd row: 6, 2

3rd row: 9, 3, 1

4th row: 19, 10, 7, ?

The pattern becomes clear when we look at the sums of each row:

1st row: 4

2nd row: 6 + 2 = 8

3rd row: 9 + 3 + 1 = 13

4th row: 19 + 10 + 7 + ? = ?

We can see that each row’s sum is increasing by 4:

4 (1st row)

8 (2nd row, 4 + 4)

13 (3rd row, 8 + 5) ?

(4th row, should be 13 + 5 = 18)

So, the sum of the 4th row should be 18.

We know the first three numbers of the 4th row: 19 + 10 + 7 = 36

To make the sum 18, we need to subtract: 36 – 18 = 18

Therefore, the missing number is 18.

To verify: 19 + 10 + 7 – 18 = 18

The missing number is 18.
