In an AP, the rth term is 3r − 2 and the common difference is 4. What is the (r + 6)th term?एक AP में rवाँ पद 3r − 2 है और सार्व अंतर 4 है। (r + 6)वाँ पद क्या होगा?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 3r + 223r + 22
The (r + 6)th term is six positions after the rth term, so add 6 common differences: aᵣ₊₆ = (3r − 2) + 6 × 4 = 3r + 22.(r + 6)वाँ पद, rवें पद से 6 स्थान आगे है, इसलिए उसमें 6 सार्व अंतर जोड़ेंगे: aᵣ₊₆ = (3r − 2) + 6 × 4 = 3r + 22।
