Can someone explain the anwser?

Step-by-step explanation:
To find each term, take the value of k (the term number) and multiply it by the square of the previous term.
[tex]c_{k}=k(c_{k-1})^{2},\ c_{0}=1\\\\c_{1}=1(c_{0})^{2}=1(1)^{2}\\c_{1}=1\\\\c_{2}=2(c_{1})^{2}=2(1)^{2}\\c_{2}=2\\\\c_{3}=3(c_{2})^{2}=3(2)^{2}\\c_{3}=12\\\\c_{4}=4(c_{3})^{2}=4(12)^{2}\\c_{4}=576\\\\c_{5}=5(c_{4})^{2}=5(576)^{2}\\c_{5}=1658880[/tex]
