Question

30) Find the 29th term of the following sequence. 27, 24, 21, 18, . . .

Answer 1

Using the arithmetic formula a1 + (n-1) d, a1 being the first term, n being the number you’re looking for and d being the common difference, you will get the answer of -57.

Here’s the work:

27 + (29 - 1) -3
27 + (28) -3
-57
