Richard design a great new hotel is hotel is tallest in the city it has 58 floors each floor has 18 room each room has two TV ho

nekit [7.7K]

There are 2088 TVs in his whole hotel.

Step-by-step explanation:

No. of floors = 58

No. of rooms = 18 per floor

Total rooms = No. of floors * No. of rooms per floor

$Total\ rooms = 58*18\\Total\ rooms=1044$

As every room has two TVs, therefore,

Total TVs = Total rooms * 2

$Total\ TVs=1044*2\\Total\ TVs=2088$

There are 2088 TVs in his whole hotel.

The 17th term of an Arithmetic sequence is 51. If the commons difference is 7, what is the first term ?

vovikov84 [41]

Answer:

The first term is:

$a_1=-61$

Step-by-step explanation:

The arithmetic sequence is defined by

$a_n=a_1+\left(n-1\right)d$

where

$a_1$ is the first term

$d$ is the common difference

the 17th term of an arithmetic sequence is 51.

i.e. $a_{17}=51$

$a_n=a_1+\left(n-1\right)d$

$a_{17}=a_1+\left(17-1\right)d$

$51=a_1+\left(17-1\right)7$ ∵ $n = 17$ , $a_{17}=51$ , $d=7$

$a_1+112=51$ ∵ $\left(17-1\right)\cdot \:\:7=112$

$a_1=-61$

Therefore, the first term is:

$a_1=-61$
