The formula for the value of nth term is 
= 3n + 1
Step-by-step explanation:
The formula of the nth term in the arithmetic sequence is
, where
- a is the first term of the sequence
- d is the common difference between each two consecutive terms
∵ The first term of an arithmetic sequence is equal to four
∴ a = 4
∵ The common difference is equal to three
∴ d = 3
- Substitute these values in the rule of the nth term
∵
∴ 
- Simplify it
∴ 
∴ 
The formula for the value of nth term is = 3n + 1

Answer:
Y=-2x
When x= -6 then y =12
Step-by-step explanation:
If y and x in direct variation then y=c*x for some constant c.
We are told
-4=c2
——> c= -2
So y= -2x
When x= -6 this becomes
Y= (-2) * (-6)
——> y = 12
$24.75
this is because 22 ÷ 8 × 9 is equal to 24.75
this is the correct answer
Answer:
C. 15
Step-by-step explanation:
-4/3x-6=-26
The first step is to add 6 to each side
-4/3x-6+6=-26+6
-4/3x =-20
Now multiply by -3/4 to isolate x.
-3/4 * -4/3x = -3/4 * -20
x = 60/4
x = 15
