A man starts repaying a loan as first instalment of Rs. $100$ . If he increases the instalment by Rs. $5$ every month, what amount he will pay in the $30^{t h}$ instalment.

$A . P .$ with the first term = $100$ and common difference = $5$ .
$30^{t h} = a + (n - 1) d$
$⟹ 100 + (30 - 1) 5$
$⟹ 100 + 29 \times 5$
$| i m p l i e s 100 + 145$
$⟹ 245$
