समांतर श्रेढ़ी \(40,37,34,\ldots\) के पहले (10) पदों का योग ज्ञात कीजिए।

Find the sum of the first (10) terms of the arithmetic progression \(40,37,34,\ldots\).

Explanation opens after your attempt
Correct Answer

A. (265)

Step 1

Concept

The tenth term is (13), so (S_{10}=\frac{10}{2}(40+13)=265). In a decreasing progression, the last term is smaller.

Step 2

Why this answer is correct

The correct answer is A. (265). The tenth term is (13), so (S_{10}=\frac{10}{2}(40+13)=265). In a decreasing progression, the last term is smaller.

Step 3

Exam Tip

दसवाँ पद (13) है, इसलिए (S_{10}=\frac{10}{2}(40+13)=265)। घटती श्रेढ़ी में अंतिम पद कम होता है।
