Question

The initial term and common difference are given. What is the nth term of the arithmetic sequence?
a1 = 6; d = (-2)

Answer 1

This is pretty much the same deal as before:

a(n) = C + dn

Where we can find C because a(1) = 6,

Therefore 6 = C + -2

What is C?

Answer 2

would it be 6-2n?

Answer 3

It cannot be because a(1) = 6, so that means 6 = 6 - 2 which isn't true.

Answer 4

It must be that C is 2 less than 6

Answer 5

heres my possible answers
8 - 2n

6 - 2n

none of these

4 - 2n

Answer 6

And which of those has a 'C" that is 2 less than 6?

Answer 7

none

Answer 8

I'd argue that 4 is 2 less than 6
