Given:


c_n=n(n+1)

Required:

To find the first four terms of the sequence.

Step-by-step explanation:

The first term is,

When n=1,


\begin{gathered} c_1=1(1+1) \\ =1*2 \\ =2 \end{gathered}

When n=2,


\begin{gathered} c_2=2(2+1) \\ =2*3 \\ =6 \end{gathered}

When n=3,


\begin{gathered} c_3=3(3+1) \\ =3*4 \\ =12 \end{gathered}
undefined
