Sequences
Write the equation:
6, 2, -2, -6, -10
t(n) = -4n + 10
solve for y
4x + y = 13
y = -4x + 13
Graph to find the solution
y = 1/2x + 2
y = 2x - 4
(4,4)
y = 2x + 5
y = 4x - 1
(3,11)
y = 3x
2x + y = 10
(2,6)

19, 22.8, 27.36, 32.832
t(n) = 15.83(1.2)n
solve for y
3x + 2y = 8
y = -3/2x + 4
Graph to find the solution
y = 2x + 1
y = -1x + 4
(1,3)
y = -3x + 10
y = 2x - 5
(3,1)
5x + 3y = -1
y = -2x + 1
(4,-7)
Write the first 4 terms of the sequence
t(n) = 2 (3)n
0.66, 2, 6, 18
Solve for y
-6x - y = -12
y = -6x + 12
Graph to find the solution
y = 3x
y = -x - 8
(-2,-6)
y = 1/2x + 6
y = x + 2
(8,10)
x = 2y + 1
3x + 4y = 23
(5,2)
What is the 235th term in the sequence
t(n) = -19 + 3n
686
Solve for x
xy + c = a
x = (a - c)/y
Graph to find the solution
2x + 3y = 12
y = x - 1
(3,2)
x = 3y - 7
x = -y + 9
(5,4)
3x - 2y = 8
y = x - 3
(2,-1)
Given t(n) = 10n - 7
Is 89 a term in the sequence? Yes or No and EXPLAIN
No, because n can not be a decimal
Solve for x
2(x + y) = b
x = b/2 -y
Graph to find the solution
y = 3x + 5
y - 3x = -2
no solution
y = 2x + 4
y = 2(x+2)
infinite solutions
6x - 2y = 12
y = 3x + 5
no solution
