Hi, 
common difference = 5, first term = -2
{{{a[n]=a[1]+(n-1)*d}}}
{{{a[n]= -2 +(n-1)*5}}}
{{{a[n]= 183 =  -2 +(n-1)*5}}}
   183 = -2 + 5(n-1)     ||Good work!, Now just solve for n
    185 = (n-1)5
     37 = (n-1)
     38 = n
{{{a[38]=-2 +(n-1)*5 = -2 + 5*37 = 183}}} ||Always recommend Checkng Your Answer
