Question 1203520
<pre>

"101rd" should be "101st" because it means "one hundred firST". 
(not "one hundred firRD")

Anyway, use the formula {{{a[n]}}}{{{""=""}}}{{{a[1]+(n-1)d}}}

with {{{n=101}}},  {{{a[1]=-5}}}, {{{d=-4}}}

Happy substituting and simplifying!  <font face="wingdings" size=6>J</font>
