Answer:
= 7n - 4
Step-by-step explanation:
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = 3 and d = a₂ - a₁ = 10 - 3 = 7 , thus
= 3 + 7(n - 1) = 3 + 7n - 7 = 7n - 4
Answer:
D

Answer:
(-4, -1/2)
Step-by-step explanation:
Just by looking at the graph I can estimate that the midpoint of AB is (-4, -1/2) but we can also use midpoint formula to get a for sure answer.
Midpoint Formula: <em>((x1 + x2)/2, (y1 + y2)/2)</em>
x: (-5 + (-3))/2
-8 / 2
x = -4
y: (-4 + 3)/2
-1 / 2
y = -1/2
