Four students compare corresponding terms in this table: Step: 1, 2, 3, 4, 5; Pattern A: 6, 8, 10, 12, 14; Pattern B: 22, 30, 38, 46, 54. Student 1 says B is always 16 more than A. Student 2 says both patterns add 2. Student 3 says B = 4 × A − 2. Student 4 says A is 4 times B. Which student's claim is correct?
