Plz solve this question
- Sum of first m terms of an A.P. is 0. If a be the first term of the A.P., then the sum of next n terms is : (A) 1 ( ) − − + m a m n m (B) 1 ( ) − − + m a m n n (C) 1 ( ) − − + n a m n n (D) 1 ( ) − − + n a m n m
- Question 1) Find the sum of first 40 positive integers divisible by 6. Question 2) Find the sum of n terms of the series (4-1/n)+4-2/n)+(4-3/n)+........ Question 3) If the sum of the first n terms of an AP is 1/2(3n²+7n), then find its nth term .Hence write the 20 th term .
