Find the sum of the first 20 terms of an arithmetic progression, if its fifth term is 11 and its 16th term is 39.
Question
Solution 1
Sure, let's solve this step by step.
Step 1: We know that the nth term of an arithmetic progression (AP) can be found using the formula: a + (n-1)d, where a is the first term, d is the common difference, and n is the term number.
