Question

51, 48, 45, 42, ...
Find the 10th term of the above sequence.

• A. 27
• B. 24
• C. 30
• D. 33

Answer 1

The correct option is B 24

The sequence follows: 51, 48, 45, 42, ...
Starting from the left,
51 - 48 = 3
48 - 45 = 3
45 - 42 = 3

So, the terms that will follow are:
5th term → 42 - 3 = 39
6th term → 39 - 3 = 36
7th term → 36 - 3 = 33
8th term → 33 - 3 = 30
9th term → 30 - 3 = 27
10th term → 27 -3 = 24
