Find the nth term of an AP from the end

n^(th) term of an AP from the end

Find the nth term of an A.P. whose 6th and 8th terms are 12 and 22 respectively :

If a_(n)=3n+4 is the nth term of an AP then find the first four terms

(i) Find the 10th term from the end of the A.P. 82, 79, 76, .... , 4 (ii) Find the 16th term from the end of the A.P. 3, 6, 9, .... 99

The 10th term and the 18th term of an A.P. are 25 and 41 respectively, then find 38th term of that A.P. Similarly if nth term is 99, find the value of n.

Find the nth term of each of the following APs: (ii) 16,9,2,-5,.... (i) 5,11,17,23,...

if nth term of an AP is 3n+2 then find the sum n terms.

Find the second term and nth term of an A.P. whose 6th term is 12 and the 8th term is 22.

Find the second term and nth term of an A.P. whose 6th term is 12 and the 8th term is 22.

The first and the last terms of an A.P.are a and l respectively.Show that the sum of nth term from the beginning and nth term from the end is a+l
