Question 448360: Which of the following equations could be used to find the nth term in the arithmetic sequence 14, 8, 2, -4, . . .?
A) an=14-8(n-1)
B) an=14+(n-1)6
C) an=14-6(n-1)
D) an=14-6+8(n-1)
(The n's are supposed to be small and below the a's. Like an exponent but on the bottom.)

---
a(1) = 14
d = -6
-------
General Form:
a(n) = a(1)+(n-1)d
For this problem:
a(n) = 14 + (n-1)(-6)
=========================
A) an=14-8(n-1)
B) an=14+(n-1)6
C) an=14-6(n-1)
D) an=14-6+8(n-1)
(The n's are supposed to be small and below the a's. Like an exponent but on the bottom.)
============
Ans: C
