Step-by-step explanation:
Given is a right angled triangle in which third side is the hypotenuse.
Therefore, by Pythagoras theorem:

3, 6, 12,<u> 24 ,</u> <u>48 </u> <=== answer
12-x(5-4k)=y
12-y=x(5-4k)
12-y/(5-4k)=x
Let's see if we can find a pattern:
Row number 1 has
seats
Row number 2 has
seats
Row number 3 has
seats
Row number 4 has
seats
Can you see the pattern? After
rows, we have added
seats.
So, the 60th row will have
