Write a formula for the general term (the nth term) of the arithmetic sequence. Do not use a resursive formula
Answer by ramkikk66(644) (Show Source): You can put this solution on YOUR website!
This is an arithmetic progression with first term as 6, and difference as -5.
(i.e. each term is the previous term -5)
In any arithmetic progression, if 'a' is the first term, and the difference is d,
Second term = a + d
3rd term = a + d + d = a + 2d
4th term = a + 3d
In general, nth term = a + (n-1)*d
So in the above series, nth term will be
Hope you got it :)
