Correct Answer

B. \(\frac{364}{5}\)

Step 1

Concept

\(a_1=\frac{14}{5}\) and \(a_3=70\), so the sum is \(\frac{364}{5}\). Use the ratio both backward and forward.

Step 2

Why this answer is correct

The correct answer is B. \(\frac{364}{5}\). \(a_1=\frac{14}{5}\) and \(a_3=70\), so the sum is \(\frac{364}{5}\). Use the ratio both backward and forward.

Step 3

Exam Tip

\(a_1=\frac{14}{5}\) और \(a_3=70\), इसलिए योग \(\frac{364}{5}\) है। आगे और पीछे दोनों दिशा में अनुपात का उपयोग करें।
