nTH term of AP

For an AP, it is given that first term (a)= 5 and Common Difference (d) = 3 and nth term = 50. Find n and sum of first n terms of AP

nth term of A.P. 5,10, 15, 20,……….n terms and nth term of A.P. 15, 30, 45, 60,…………n terms are same.

Find the nth term of an AP from the end

By Principle of Mathematical Induction : nth term of A.P. whose first term is 'a' and common difference is 'd' is ______

The nth term of an AP. Is (3+n)/(4) , then the sum of first 105 terms is

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

The nth term of an AP is 5n+ 2. Find the common difference.

The nth term of an AP is (7-4n). Find its common difference.

The nth term of an AP is (3n +5). Find its common difference.
