The Correct Option is C

Solution and Explanation


Concept: This sequence follows an alternating pattern in the differences between consecutive terms, which helps in predicting the next number. Step 1:Compute consecutive differences:
\[ 34 - 36 = -2 \] \[ 30 - 34 = -4 \] \[ 28 - 30 = -2 \] \[ 24 - 28 = -4 \]
Step 2:Identify the pattern.
The differences follow an alternating sequence: \[ -2, -4, -2, -4, \ldots \]
Step 3:Continue the pattern.
After 24, the next difference should be -2: \[ 24 - 2 = 22 \]
Final Answer: 22
