A₁ = 9
a₂ = 9+2 → a₂ = a₁ + 2. Since it's an AP, d, the common difference is 2
1) Then the recursive formula is :
a(n) = a(n-1) + 2
2) Explicit formula:
It's an AP, with first term a₁, d= common difference and n = number of term, which is the number of rows in this problem.
the value of the nth term is given by the formula is:
value of nth term = a₁ + (n-1).d
3) Number of seats in the 12th row:
9 + (12-1).2 = 31 seats
Answer:
b = 5
Step-by-step explanation:
Since you are given two points, you can find the slope (m). Use the equation for slope to find it.
Plug the points into the equation and solve.
Now that you have the slope, you can use it and one of the points given to you to find the equation of the line by using point-slope form.
Plug in the slope and one point and solve.
The equation for the line is (y = -2x + 5). The value for b is 5.
