Lee is staying at a hotel. The cost of the first night is $240. The cost for each night after that is $210. Let y represent the

GenaCL600 [577]

A) The situation represents an arithmetic sequence because the successive y-values have a common difference of 210.

F(1) = 240 +210

F(2) = 240 +2(210)

F(3) = 240+3(210)

F(x)= 240 +210x.

1. Find the common difference and find the 75th term of the arithmetic sequence: 3, 6, 9, 12, ....

Ymorist [56]

Answer:

$\boxed{225}$

Step-by-step explanation:

Arithmetic sequence

$Un = a + (n - 1)b$

First step, find its difference

$b = U_2 - U_1$

$b = 6 - 3$

$b = 3$

So, we get

$a = 3$

$b = 3$

Finally, Let's find the 75th term

$U_{75} = 3 + (75 - 1)3$

$U_{75} = 3 + (74)3$

$U_{75} = 3 + 222$

$U_{75} = 225$

One number is 16 more than a second number. The sum of the first number and twice the second number is 139. What is the answer ?

Nezavi [6.7K]

Answer first number = 57 second number = 41
x= 16 + y
x + 2y = 139

16+ y + 2y =139
16 + 3y =139
16-16 +3y = 139-16
3y = 123
3/3y = 123/3
y= 41

x= 16+y
x = 16+41
x= 57
