Question

I’ve worked out that the 1st term is -5 but can’t work out the rest. I thought it was -77 but it’s wrong

Answer 1

Answer:
1st term: 3(1) - 8 = 3-8= -5
10th term: 3(10) - 8= 30-8= 22
100th term: 3(100)-8= 300-8= 292

Explanation:
Substitute the term number (e.g. 10) in the place of n

Hope this helped! :)

(i) n = 1 , 3n - 8

       = 3 x 1 - 8

                 = -5

(ii) n = 10 , 3n - 8

        = 3 x 10 - 8

                    =22

(iii) n = 100 , 3n - 8

         = 3 x 100 - 8

               = 300 - 8

                     = 292
