Answer:

bhai your question is not clear please clear

Answer 2

Answer:

Sum = $S = (10) {2a + ( n-1 )d$

Step-by-step explanation:

Since you have not given the AP, I will take the first term = a, and common difference = d.

Given that, n = 20

Sum = $S = \frac{n}{2} (2a + (n-1) d)$

              = (10) {2a + (n-1) d}                    (As n = 20, n/2 = 10)

Which is your answer.

Thank You!!
