Short Answer

Expert verified

B) The number that follows 20 in the arithmetic sequence is 23.

Step by step solution

Step 1. Given Information.

The given arithmetic sequence is 8, 11, 14, 17, 20, …

Step 2. Calculation.

A sequence is said to be arithmetic when the difference between the consecutive terms is always the same.

Here the difference between the first two terms is $11 - 8 = 3$

The difference between the next two terms is $14 - 11 = 3$

So, the common difference is 3.

The next term after 20 in the arithmetic sequence is $20 + 3 = 23$

Step 3. Conclusion.

Hence, the number that follows 20 in the arithmetic sequence is 23.
