•  $\frac{5n+3}{-2n-15}$  

A number sequence has nth term 6n + 3.

Sara says that 1008 is a term in this sequence.

Is she correct?

• Incorrect, because n should be a positive integer.Here n=167.5

• correct, n= 167.5 round off n= 168

• Incorrect, answer is 6(1008)+3= 6051

• correct, answer is 6(1008)+3= 6051, so n is a positive integer
