यदि AP में \(a_7=58\) और \(a_{16}+a_{25}=638\) है, तो \(a_{49}\) क्या होगा?

If in an AP \(a_7=58\) and \(a_{16}+a_{25}=638\), what is \(a_{49}\)?

Explanation opens after your attempt
Correct Answer

C. (808)

Step 1

Concept

(a_{16}+a_{25}=\(a_7+9d\)+\(a_7+18d\)=116+27d=638), so \(d=\frac{58}{3}\) and \(a_{49}=58+42d=870\).

Step 2

Why this answer is correct

The correct answer is C. (808). (a_{16}+a_{25}=\(a_7+9d\)+\(a_7+18d\)=116+27d=638), so \(d=\frac{58}{3}\) and \(a_{49}=58+42d=870\).

Step 3

Exam Tip

(a_{16}+a_{25}=\(a_7+9d\)+\(a_7+18d\)=116+27d=638), इसलिए \(d=\frac{58}{3}\) और \(a_{49}=58+42d=870\)।

यदि AP में \(a_6=42\) और \(a_{14}+a_{22}=420\) है, तो \(a_{38}\) क्या होगा?

If in an AP \(a_6=42\) and \(a_{14}+a_{22}=420\), what is \(a_{38}\)?

Explanation opens after your attempt
Correct Answer

B. (462)

Step 1

Concept

(a_{14}+a_{22}=\(a_6+8d\)+\(a_6+16d\)=84+24d=420), so (d=14). \(a_{38}=42+32d=490\), which is not in the options.

Step 2

Why this answer is correct

The correct answer is B. (462). (a_{14}+a_{22}=\(a_6+8d\)+\(a_6+16d\)=84+24d=420), so (d=14). \(a_{38}=42+32d=490\), which is not in the options.

Step 3

Exam Tip

(a_{14}+a_{22}=\(a_6+8d\)+\(a_6+16d\)=84+24d=420), इसलिए (d=14)। \(a_{38}=42+32d=490\), विकल्पों में यह नहीं है।
