Answer:
aₙ = 207+9*(n-1)
Step-by-step explanation:
a1 = 207+9*(1-1) = 207
a2 = 207+9*(2-1) = 216
a3 = 207+9*(3-1) = 225
....
aₙ = 207+9*(n-1)

Answer:
7/6
Step-by-step explanation:
y2-y1/x2-x1(slope formula)
plug in numbers
12-5=7
8-2=6
hence 7/6
Step-by-step explanation:
The sum of two opposite interior angles equals an exterior angle
50+?=115
