Reena's monthly salary forms an AP: ₹8000, ₹8500, ₹9000, $\ldots$. What will be her monthly salary in the 15th year?
A₹14500
B₹15000
C₹15500
D₹16000
Answer & Solution
Correct answer: B. ₹15000
Here $a=8000$ and $d=500$. Using $a_n=a+(n-1)d$, we get $a_{15}=8000+(15-1)\times 500=8000+7000=15000$. Hence her salary in the 15th year is ₹15000.
