The teacher gave this pattern to the class: the first term is 5 and the rule is add 4, subtract 1. Each student says one number. The first student says 5. Victor is tenth in line. What number should Victor say?
To determine the number that Victor should say, we need to apply the given rule to each term in the pattern and identify the term that corresponds to Victor's position in the sequence.
The pattern starts with the first term being 5. According to the given rule (add 4, subtract 1), we can apply this rule to each subsequent term to generate the pattern:
Term 1: 5
Term 2: 5 + 4 - 1 = 8
Term 3: 8 + 4 - 1 = 11
Term 4: 11 + 4 - 1 = 14
Term 5: 14 + 4 - 1 = 17
Term 6: 17 + 4 - 1 = 20
Term 7: 20 + 4 - 1 = 23
Term 8: 23 + 4 - 1 = 26
Term 9: 26 + 4 - 1 = 29
Term 10: 29 + 4 - 1 = 32
From the pattern, we find that the 10th term is 32. Therefore, Victor, who is tenth in line, should say the number 32.
