a fireplace contains 54 bricks along its bottom row. if each row above decreases by 3 bricks, what is the function that shows the bricks on the 10th row

27 bricks

Step-by-step explanation:

y= 54- 3(x-1)

y= 57- 3x

is the function, y= number of bricks on the xth row, x= row number above the bottom one

x=10 ⇒ y= 57 - 3*10 ⇒ y= 27 bricks

the terms of a geometric sequence can be found by beginning with the first term and multiplying by the common ratio repeatedly. a recursive formula for a geometric sequence with common ratio r is given by an=ran−1 a n = r a n − 1 for n≥2 n ≥ 2 .
