Find the 9th term in the following arithmetic sequence
-7, -1, 5, 11

41

Step-by-step explanation:

1. Multiply 5 by 6 in order to get to the 9th number. (5 places away, 4 were given.) Also, notice that the difference between all of the numbers are consistently 6.

2. Add 30 to 11, which gives you 41.

Step-by-step explanation:

calculate the difference between each number and find out how many are left in the sequence and multiply by that

in this case the difference was 6 and you needed 5 more until you hit the ninth number so 5*6+30 30+11=41
