Correct Answer

C. (22)

Step 1

Concept

The increase over six gaps is (24), so (d=4) and (a_7=10+3(4)=22). \(a_7\) lies between the two given terms.

Step 2

Why this answer is correct

The correct answer is C. (22). The increase over six gaps is (24), so (d=4) and (a_7=10+3(4)=22). \(a_7\) lies between the two given terms.

Step 3

Exam Tip

छह अंतरों में वृद्धि (24) है, इसलिए (d=4) और (a_7=10+3(4)=22)। \(a_7\) दोनों दिए पदों के बीच आता है।
