Find the 10th term in the following arithmetic sequence if the constant being added is

-12:20,8,-12,-16

10th term = - 88.

Step-by-step explanation:

This is an arithmetic sequence with first term = 20 and common difference - 12.

nth term = a1 + (n - 1) d

10th term = 20 + (10-1) * -12

= 20 - 108

= - 88.

Find the 10th term in the following arithmetic sequence if the constant being added is - 12

Step-by-step explanation:

20 - 12 = 8

8 - 12 = - 4

-4 - 12 = - 16

So the sequence will be

20; 8; - 4; - 16

an = 20 - 12 (n - 1)

a10 = 20 - 12 (10 - 1) = - 88
