## Sequences and Series: Arithmetic Progression **What is an Arithmetic Progression (AP)?** An AP is a sequence of numbers where the difference between consecutive terms is constant. This constant is called the common difference, $d$. **Key Points** 1. The first term is denoted by $a$. 2. The common difference is $d = a_2 - a_1$. 3. The $n^{th}$ term is given by $a_n = a + (n-1)d$. 4. The sum of t [Preview only]
