 My research focuses on analyzing the class of Perrin-type primality tests- **Lucas-Type Sequence**:
 
 ## [Lucas-Type Sequence](https://oeis.org/wiki/Lucas_sequences)
-Each primality test is a sequence with two parameters, $c_0$ and $c_1$, and initial condition $V_0$ and $V_1$
+Each primality test is a sequence with two parameters, $c_0$ and $c_1$, and initial condition $V_0$ and $V_1$, and the general form is:
 
 $$V_{n+2} = c_1 V_{n+1} + c_0 V_{n}, \quad V_{0} = 2, \quad V_{1} = c_1$$
