N represents the number of term A) for the 1st three terms, just substitute n with 1,2 and 3 1st term: 3(1) + 2 = 5 2nd term: 8 3rd term: 11 B) 10th term: 3(10)+2= 32 You can check the answer by using the method: if n is the number of term, then 3n would represent multiples of 3. In this question, the answer will always be 2 more than any multiples of 3 (given n is a number)
