To find the 3rd term, just replace the 'n' with 3.
Therefore:
t(3) = 6(3) + 2
t(3) = 18 + 2
t(3) = 20.
The 3rd term is 20.
The width of rectangle is 21 meters.
Step-by-step explanation:
Given,
Perimeter of rectangle = 98 meters
Width of rectangle = w
Length of rectangle = w+7
Perimeter of rectangle = 2(Length+Width)
Perimeter = 

Dividing both sides by 4

Width of rectangle = 21 meters
The width of rectangle is 21 meters.

Step-by-step explanation:
Hmm, I'd say it's the first option.
Answer:
Adult ticket: $7 Student ticket: $11
Step-by-step explanation:
First, we set up our equations.
x (adult ticket) y(student ticket)
For the first day, 11x + 3y = 110
For the second day, 3x + 6y = 87
Then we solve.
(-2)11x + 3y =110
Equals
-22x - 6y = -220
Add them
-22x - 6y = -220
3x + 6y = 87
This equals
-19x = -133
x = 7
Plug in to find y
3(7) + 6y = 87
21 + 6y = 87
6y = 66
y= 11
