what is the nth term for 12 10 8 6?

Answer 1

The nth term would be -2n+14

nth terms: 1 2 3 4

Sequence:12 10 8 6

This sequence has a difference of -2

Therefore it would become -2n. Replace n with 1 and you would get -2.

To get to the first term you have to add 14. Therefore the sequence becomes -2n+14.

To check your answer replace n with 2, 3 or 4. You will still obtain the number in the sequence that corresponds to the nth term.
