Study the sequence of patterns formed by squares and the table below. Pattern no.No. of squaresExternal perimeter $1$$3$$8$ $2$$8$$12$ $3$$15$$16$ $4$$24$$20$ $\vdots $$\vdots $$\vdots $ $8$$p$$q$ $\vdots $$\vdots $$\vdots $ $n$${{S}_{n}}$${{P}_{n}}$ State the values of $p$ and $q$. Express ${{S}_{n}}$ and ${{P}_{n}}$ in terms of $n$. Pattern $k$ has an external perimeter of $104$ units. Find the value of $k$.

Accepted Answer

(a) $p = 80$, $q = 36$; (b) $S_n = (n+1)^2 - 1$, $P_n = 4n + 4$; (c) $k = 25$
