Question

Look at this series: 22, 21, 23, 22, 24, 23, ….. What number should come next?

• A. \( 22 \)
• B. \( 24 \)
• C. \( 21 \)
• D. \( 25 \)

Hint:

When solving sequences, check for alternating patterns in addition and subtraction or any similar trends.

Answer 1

The Correct Option is B

Step 1: Analyzing the pattern.
The given sequence is: 22, 21, 23, 22, 24, 23, .....
The pattern alternates between subtraction and addition:
\( 22 - 1 = 21 \) \( 21 + 2 = 23 \) \( 23 - 1 = 22 \) \( 22 + 2 = 24 \) \( 24 - 1 = 23 \)
Step 2: Identifying the next term.
Following this alternating pattern, we now add 2 to 23:
\[ 23 + 2 = 25. \]
Thus, the next term is 25.
