Match List-I with List-II (Symbols have their usual meaning)

List-I (Expression) List-II (Definitions)
(A) $a_n = a + [n-1]d$ (I) $n^{th}$ term of Geometric Progression
(B) $s_n = \frac{n}{2}[2a + (n-1)d]$ (II) Sum of n terms of Geometric Progression
(C) $a_n = ar^{n-1}$ (III) $n^{th}$ term of Arithmetic Progression
(D) $s_n = a\left(\frac{r^n - 1}{r-1}\right)$ (IV) Sum of n terms of Arithmetic Progression
