Question

Find the nth term of the arithmetic sequence where a1 = 5000 and d = -100.

Answer 1

The nth term of any arithmetic sequence is

an = a1 + (n-1)*d

In this case a1 = 5000 and d = -100, so

an = a1 + (n-1)*d

an = 5000 + (n-1)*(-100)

Simplify this to get your answer

Answer 2

= -100n + 5100.
