The teacher gave this pattern to the class. the first term is 5 and the rule is add 4, subtract i. Each student says one number. The first student Victor is line. What number should Victor say?
He should say 36. The first term is 5 so make sure not to add it again. First its 5 plus 4 minus 1 which is nine. Then is 9 plus 4 minus 1 which is 12. And so on.
