Answer:
c(1) = -15
c(n) = c(n - 1) + 4
Step-by-step explanation:
Given arithmetic sequence is,
-15, -11, -7, -3...........
Common difference between each successive and previous term is,
d = -11 - (-15)
= -11 + 15
= 4
Since recursive formula of the arithmetic sequence is represented by,
a₁ = First term of the sequence
a(n) = a(n - 1) + d
where a(n) is the nth term and a(n-1) is the previous term of the nth term.
Form the given sequence,
c₁ = -15
c(n) = c(n - 1) + 4
The solution is where the two lines meet. From the the graph, it looks like
(1, -1)
11.-53000 12.-.000992 13.-.041
4-2 is 2
and 5-3 is 2
when you add or subtract fractions, you don't change the denominator (bottom number in fraction)
so the answer is 2 2/8
Answer:
60 degrees
Step-by-step explanation:
set up like 240-120
240-120=120
120 divided by 2 equals 60
therefor, the angle is 60 degrees
