Let's fill in the missing numbers in Pascal's Triangle step by step.

 

Step 1: Understand the pattern of Pascal's Triangle

Each number in Pascal's Triangle is the sum of the two numbers directly above it.

1.First number and last number of any row are always 1.

2.The second and second-last numbers can be found by adding the two numbers above them.

 

Step 2: Fill in the missing numbers

We need to find the missing numbers in the fifth row.

The first number is 1 and the last number is 1 (fixed).

 

Let's focus on the second and fourth numbers (marked as ?).

The second number is directly below the pair (1) and (3) from the previous row. So, ( 1 + 3 = 4 ). So, the second number is 4.

The fourth number is directly below the pair (3) and (1) from the previous row. So, ( 3 + 1 = 4 ). So, the fourth number is 4.
