Answer:
3, 5, 7, 9, 11, .........
Step-by-step explanation:
Given
= n(n + 2) , then
S₁ = 1(1 + 2) = 1(3) = 3 ⇒ a₁ = 3
S₂ = 2(2 + 2) = 2(4) = 8
S₃ = 3(3 + 2) = 3(5) = 15
Thus
a₂ = S₂ - S₁ = 8 - 3 = 5
a₃ = S₃ - S₂ = 15 - 8 = 7
The first 3 terms are 3, 5, 7
This is an AP with common difference d = 2, then
a₄ = a₃ + 2 = 7 + 2 = 9
a₅ = a₄ + 2 = 9 + 2 = 11
and so on
Slope:2
y intercept: 5
so if your test has like a graph the dot will be at y=5
Answer:
you would solve using x and y intercepts.
Step-by-step explanation:
for the X intercept, Y=0
3x=-18. you divide by three on both sides
x=-6. (-6,0)
the for the y intercept, X=0
+9y=-18. you divide 9 on both sides.
y=-2. (0,-2)
then you graph both and connect the points on the x and y axis.
