Answer 2

Answer:

9th Row in a Pascal's Triangle: 1 8 28 56 70 56 28 8 1

Step-by-step explanation:

As we know the 8th row is: 1 7 21 35 35 21 7 1

So, in 9th row fist and last columns will occupy 1,

next numbers will be formed as follows

1  +  7   = 8

7  + 21  = 28

21 + 35 = 56

35 + 35 = 70

35 + 21  = 56

21  +  7   =  28

7  +   1    =  8

Hence, 9th row will be:  1 8 28 56 70 56 28 8 1
