The number of seats in each row of an auditorium increases by 2 from one row to the next. if there are 48 seats in the first row, how many seats are there in the 60th row?

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

8(-10x+3.5y-7)

8×-10x + 8×3.5y + 8×-7

-80x + 28y - 56

therefore

-80x+28y-56 is the correct answer

439400

step-by-step explanation:

130^2 = 16900

16900*26 = 439400
