Question

Find the missing number in the sequence: \[ 285, 253, 221, 189, ? \]

• A. \( 150 \)
• B. \( 182 \)
• C. \( 157 \)
• D. \( 156 \)

Hint:

For missing numbers in a sequence, check for constant differences or multiplicative patterns.

Answer 1

The Correct Option is C

Step 1: Identifying the pattern.
Observing the given sequence: \[ 285, 253, 221, 189, ? \] The difference between consecutive terms is: \[ 285 - 253 = 32, \quad 253 - 221 = 32, \quad 221 - 189 = 32 \] Step 2: Finding the next term.
\[ 189 - 32 = 157 \] Thus, the correct answer is (C) \( 157 \).
