1. Define the sequence starting from $$ -180^{\circ} $$ and increasing by $$ 45^{\circ} $$.
2. The $$ n $$-th term of the sequence can be written as  
   $$
   a_n = -180^{\circ} + 45^{\circ} \cdot n \quad \text{for } n = 0, 1, 2, \ldots
   $$
3. Determine the number of steps needed to reach $$ 180^{\circ} $$:  
   Set  
   $$
   -180^{\circ} + 45^{\circ} \cdot n = 180^{\circ}.
   $$
   Solve for $$ n $$:
   $$
   45^{\circ} \cdot n = 180^{\circ} + 180^{\circ} = 360^{\circ},
   $$
   $$
   n = \frac{360^{\circ}}{45^{\circ}} = 8.
   $$
4. List all angles by calculating each term for $$ n = 0 $$ to $$ 8 $$:
   $$
   \begin{aligned}
   n=0: \quad & -180^{\circ} + 45^{\circ} \cdot 0 = -180^{\circ}, \
   n=1: \quad & -180^{\circ} + 45^{\circ} \cdot 1 = -135^{\circ}, \
   n=2: \quad & -180^{\circ} + 45^{\circ} \cdot 2 = -90^{\circ}, \
   n=3: \quad & -180^{\circ} + 45^{\circ} \cdot 3 = -45^{\circ}, \
   n=4: \quad & -180^{\circ} + 45^{\circ} \cdot 4 = 0^{\circ}, \
   n=5: \quad & -180^{\circ} + 45^{\circ} \cdot 5 = 45^{\circ}, \
   n=6: \quad & -180^{\circ} + 45^{\circ} \cdot 6 = 90^{\circ}, \
   n=7: \quad & -180^{\circ} + 45^{\circ} \cdot 7 = 135^{\circ}, \
   n=8: \quad & -180^{\circ} + 45^{\circ} \cdot 8 = 180^{\circ}.
   \end{aligned}
   $$
5. The complete sequence is:  
   $$
   -180^{\circ},\ -135^{\circ},\ -90^{\circ},\ -45^{\circ},\ 0^{\circ},\ 45^{\circ},\ 90^{\circ},\ 135^{\circ},\ 180^{\circ}.
   $$
The sequence of angles is: -180°, -135°, -90°, -45°, 0°, 45°, 90°, 135°, 180°.
