Answer:

90 mirrors

If 5 mirrors=30 mins

then x=9 hrs

therefore 30÷60 to covert it to hours is equal to 0.5hr

5×9hrs÷0.5hr=90

therefore x=90

Answer:

<h2>          \bold{a_n=-7n+39}</h2>

Step-by-step explanation:

25 - 32 = -7  and 18 - 25 = -7

It means an arithmetic sequence with common difference d = -7

a_n = a_1+d(n-1)\\\\a_1=32\\d=-7\\\\a_n=32+(-7)(n-1)\\\\a_n = 32-7n+7\\\\\underline{a_n=-7n+39}
