What is the Nth term of these numbers 80, 120, 160

Mathematics
1 answer:
grin007 [14]3 years ago
5 0

Answer:

Step-by-step explanation:

80,120,160.....

This is an arithmetic sequence

common difference (d) = 2nd term - 1st term

                                      = 120 - 80 = 40

first term (a) = 80

nth term = a + (n-1)d

              = 80 + (n-1)*40

              = 80 + 40n -40

              = 40 + 40n

ANSWER: x=12
EXPLANATION:
9+x/6=11
(54+x)/6=11 (finding common denominator)
x/6=11-54/6 (rearranging terms)
x/6=(66-54)/6 (finding common denominator so 6 gets cancelled from both the sides)
x=12

Which of the following best defines an angle?
scoray [572]

Answer:

Third option

Step-by-step explanation:

The first definition is not as broad as it should be, therefore, while an angle does meet that criteria, it's not a general definition, hence, it is incorrect. The second one is incorrect as well because a parabola has a vertex, and it is certainly not an angle. This definition is not specific enough, so it will be eliminated. The last one is again, too specific. The third one is the best answer because it is broad enough while still being specific.
