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?

stated rule:

add 4, then subtract 1
effective rule:
add 3

5, 8, 11, 14, 17, ....

what do you think ?

17

I think that it is five because subtract one

The answer is 32

To find the number that Victor should say, we need to apply the given rule to the first term multiple times until we get to the tenth term.

Given that the first term is 5 and the rule is to add 4 and then subtract 1, we can calculate the sequence as follows:

Term 1: 5
Term 2: 5 + 4 = 9
Term 3: 9 - 1 = 8
Term 4: 8 + 4 = 12
Term 5: 12 - 1 = 11
Term 6: 11 + 4 = 15
Term 7: 15 - 1 = 14
Term 8: 14 + 4 = 18
Term 9: 18 - 1 = 17
Term 10: 17 + 4 = 21

Therefore, Victor, who is tenth in line, should say the number 21.
