SOLUTION: Write the nth term of the geometric sequence as a function of n. {{{ a[1] = -3}}} , {{{a[k+1] = -4a[k]}}}

Algebra ->  Sequences-and-series -> SOLUTION: Write the nth term of the geometric sequence as a function of n. {{{ a[1] = -3}}} , {{{a[k+1] = -4a[k]}}}      Log On

Substitute n=1




So the common ratio is 

nth term:
