Identify a numerical pattern and write a rule that matches it.
Pick the rule that really fits the pattern
Problem
For \(x~=~1,~2,~3,~4\) and \(y~=~5,~8,~11,~14\), test each candidate rule against every pair and report the letter of the rule that fits.
A. \(y~=~3x~+~2\) B. \(y~=~x~+~4\) C. \(y~=~5x\) D. \(y~=~2x~+~3\)
Big Picture
What this problem is really about
A rule earns confidence by surviving several substitutions, not by matching the first pair by coincidence. Use a strategically chosen input to eliminate expressions quickly, but keep checking any survivor against all remaining input–output pairs. This turns the task into a complete fit test: every listed input must produce its paired output under the same expression.
