Question 974040
General term is  {{{3+(n-1)5}}}.  You want to know if a whole number solution is for {{{3+(n-1)5=310}}};  suspect not, because 3 is a factor on the left but is not a factor on the right.


{{{3+3n-5=310}}}
{{{3n-2=310}}}
{{{3n=312}}}
{{{n=14}}}---------whole number.


Yes, 310 is a term of the sequence.
