Given First term of A.P =16
Common difference =9-16=-7
Now nth term of the A.P = a+(n-1)d
= 16+(n-1)-7
=16-7n+7
=23-7n .
Therefore , 23-7n is the n th term of given A.P
Common difference =9-16=-7
Now nth term of the A.P = a+(n-1)d
= 16+(n-1)-7
=16-7n+7
=23-7n .
Therefore , 23-7n is the n th term of given A.P
