Question 1179191

Write a formula for the sequence below, then find {{{a[10]}}}

{{{-4}}},{{{-12}}},{{{-36}}},{{{-108}}}.......

{{{-12/-4=3}}}
{{{-36/-12=3}}}=> common ratio is {{{3}}}


nth term formula

{{{a[n]=-4*3^(n-1)}}}

find {{{a[10]}}}

{{{a[10]=-4*3^(10-1)}}}

{{{a[10]=-4*3^9}}}

{{{a[10]=-78732}}}
