Answer:
Option C.
Step-by-step explanation:
It is given that the first term of the arithmetic sequence is 8 and second term is 5.
We know that the explicit equation of an AP is
, where n is an integer greater than or equal to 1.
where, a is first term and d is common difference.
So, domain of this explicit equation is all integers where n ≥ 1.
Therefore, the correct option is C.
Answer:
-The equation for the problem:
Step-by-step explanation:
-First, you need determine the slope of a line:
(where
is the first coordinate and
is the second coordinate).
-Use both points and
for the formula:
-After you have found the slope, use the point-slope formula and use the slope and the first coordinate, which is
, to solve the equation and put it in slope-intercept form:
-Solve:
So, therefore the equation is .
