The Correct Option is C
Solution and Explanation
Concept:
Look for a consistent multiplication pattern.
Step 1: Observe the pattern.
\[ 13 \times 3 = 39 \] \[ 39 \times 3 = 117 \] \[ 117 \times 3 = 351 \] \[ 351 \times 3 = 1053 \] \[ 1053 \times 3 = 3159 \]
Step 2: Identify missing term.
\[ 117 \times 3 = 351 \]
Hence, the missing number is 351.
Step 1: Observe the pattern.
\[ 13 \times 3 = 39 \] \[ 39 \times 3 = 117 \] \[ 117 \times 3 = 351 \] \[ 351 \times 3 = 1053 \] \[ 1053 \times 3 = 3159 \]
Step 2: Identify missing term.
\[ 117 \times 3 = 351 \]
Hence, the missing number is 351.
