Question 405565
{{{S = 6n-5}}}

Work out the first three terms of this sequence"

The first three terms are found by substituting {{{n}}} with {{{1}}} (first term), {{{2}}} (second term) and {{{3}}} (third term)


so

{{{n=1}}} gives: {{{S=6*1-5 = 6-5 = 1}}}

{{{n=2}}} gives: {{{S=6*2-5= 12-5 = 7}}}

{{{n=3}}} gives: {{{S=6*3-5 = 18-5 = 13}}}


So the first three terms of S are {{{1}}}, {{{7}}} and {{{13}}}.
