An arithmetic sequence is represented by the linear function f(n)=−8n+19. Find the first term, a1, and the common difference, d, of the sequence.(1 point) a1= d=
To find the first term (a1) and the common difference (d) of the arithmetic sequence represented by the linear function f(n) = -8n + 19, we first need to recognize the pattern in the function.
In an arithmetic sequence, the general formula is given by: an = a1 + (n-1)d, where an is the nth term, a1 is the first term, n is the term number, and d is the common difference.
Comparing this formula with the given linear function f(n) = -8n + 19, we can see that a1 = 19 and d = -8.
Therefore, a1 = 19 and d = -8.
