Question 1189532


Write the formula describing the sequence {{{6}}},{{{14}}},{{{22}}},{{{30}}}.


sequence:..... {{{6}}}.......{{{14}}}.......{{{22}}}.......{{{30}}}
differences:.........{{{8}}}........{{{8}}}.........{{{8}}} => {{{d=8}}}


The formula for {{{n}}}th term of an arithmetic progression is 

{{{a[n]=a[1]+(n-1)*d}}}

 In this example we have {{{d=8}}} and {{{a[1]=6}}}, than

{{{a[n]=6+(n-1)*8}}}

{{{a[n]=6+8n-8}}}

{{{a[n]=8n-2}}}
