To find the common difference d, use the formula a1+4d=a5. For us, a1 is 10 and a5 is 38. 10+4d=38 Now we can solve for d. 4d=28 d=7 Add the common difference to the first term to get the second term. a2=a1+d=10+7=17

There is no need for formulas in this case, because the numbers are small as are the differences between the terms involved. There are four steps to go from the second to the 6th term. each step is the same size (arithmetic seq). In those four steps you go from 107 to 87, so 20 less. That is 20/4=5 less each step. I think you know now how to find the ninth number :)

so 122 then?

No, because the sequence decreases: 2th term is 107, 6th is 87. Each next term is 5 less than the current one.

ops sorry, wrong way, so 72 lmao
