Question 1125134

{{{f(n)=4*2(n-1)}}}

Assume {{{n}}} begins with {{{1}}}.

{{{f(1)=4*2(1-1)}}}.........if {{{n=1}}}

{{{f(1)=4*2(0)}}}

{{{f(1)=highlight(0)}}}-> first term


{{{f(2)=4*2(2-1)}}}.........if {{{n=2}}}

{{{f(2)=4*2(1)}}}

{{{f(2)=highlight(8)}}}-> second term



{{{f(3)=4*2(3-1)}}}.........if {{{n=3}}}

{{{f(3)=4*2(2)}}}

{{{f(3)=highlight(16)}}}-> third term



{{{f(4)=4*2(4-1)}}}.........if {{{n=4}}}

{{{f(4)=4*2(3)}}}

{{{f(4)=highlight(24)}}}-> fourth term
