The number of windows on each floor form an arithmetic sequence; 124 windows on the first floor, 116 windows on the second floor

zubka84 [21]

Answer:

Formula is 132 - 8n, and there are 52 windows on 10th floor.

Step-by-step explanation:

difference = 116-124 = -8 ( 8 less windows for every floor you go up)

the first fllor has 124 windows

Formula:

$a_{1} = 124$

$a_{n} = 124 + (-8)(n - 1)$ = 132 - 8n

10th Floor:

$a_{10} = 124 + (-8)(10 - 1) = 124 + (-8)(9) = 124 - 72 = 52 windows$
