Question 1/4 Expert Mathematics Arithmetic Progressions (AP) Finding the $n$th term of an AP Class 10 Level 66

यदि \(a_n=10n+19\) और \(a_m=349\) है, तो \(a_{m+18}\) क्या होगा?

If \(a_n=10n+19\) and \(a_m=349\), what is \(a_{m+18}\)?

Explanation opens after your attempt
Correct Answer

C. (529)

Step 1

Concept

From (10m+19=349), (m=33). \(a_{51}=10\times51+19=529\).

Step 2

Why this answer is correct

The correct answer is C. (529). From (10m+19=349), (m=33). \(a_{51}=10\times51+19=529\).

Step 3

Exam Tip

(10m+19=349) से (m=33)। \(a_{51}=10\times51+19=529\)।

Question 2/4 Expert Mathematics Arithmetic Progressions (AP) Finding the $n$th term of an AP Class 10 Level 66

यदि किसी समान्तर श्रेणी में \(a_{4p}=188\), \(a_p=56\) और (d=11) है, तो (p) का मान क्या होगा?

If in an AP \(a_{4p}=188\), \(a_p=56\), and (d=11), what is the value of (p)?

Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

\(a_{4p}-a_p=3pd=132\) so (33p=132) and (p=4). In index questions first find the position gap.

Step 2

Why this answer is correct

The correct answer is B. (4). \(a_{4p}-a_p=3pd=132\) so (33p=132) and (p=4). In index questions first find the position gap.

Step 3

Exam Tip

\(a_{4p}-a_p=3pd=132\) इसलिए (33p=132) और (p=4)। सूचकांक वाले प्रश्न में स्थानों का अंतर पहले निकालें।

If \(a_n=8n+15\) and \(a_m=239\), what is \(a_{m+16}\)?

Explanation opens after your attempt
Correct Answer

B. (367)

Step 1

Concept

From (8m+15=239), (m=28). \(a_{44}=8\times44+15=367\).

Step 2

Why this answer is correct

The correct answer is B. (367). From (8m+15=239), (m=28). \(a_{44}=8\times44+15=367\).

Step 3

Exam Tip

(8m+15=239) से (m=28)। \(a_{44}=8\times44+15=367\)।

Question 4/4 Expert Mathematics Arithmetic Progressions (AP) Finding the $n$th term of an AP Class 10 Level 65

यदि \(a_{3m}=152\), \(a_m=56\) और (d=8) है, तो (m) का मान क्या होगा?

If \(a_{3m}=152\), \(a_m=56\), and (d=8), what is the value of (m)?

Explanation opens after your attempt
Correct Answer

B. (6)

Step 1

Concept

\(a_{3m}-a_m=2md=96\), so (16m=96) and (m=6). In index questions, first check the position gap.

Step 2

Why this answer is correct

The correct answer is B. (6). \(a_{3m}-a_m=2md=96\), so (16m=96) and (m=6). In index questions, first check the position gap.

Step 3

Exam Tip

\(a_{3m}-a_m=2md=96\), इसलिए (16m=96) और (m=6)। सूचकांक वाले प्रश्न में स्थानों का अंतर पहले देखें।
