Find the 30th term of the arithmetic progression 600 + 650 + 700 + 750 + ...

1. An arithmetic progression (AP) is given as $600 + 650 + 700 + 750 + \dots$
The first term is $a = 600$.
The common difference is $d = 650 - 600 = 50$.

a) The 30th term of the AP

Step 1: Use the formula for the $n$-th term of an AP, $T_n = a + (n-1)d$.
Here, $n = 30$.
