Question

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?

Answer 1

Victor should say 35, if I am correct

Answer 2

"the rule is add 4, subtract 1" ---> in effect is adding 3

term(n) = 5 + 3n

so term(10) = 5 + 3(10) = 35

Emma is correct

Answer 3

35 is not an option your choices are 17 19 20 and 21

Answer 4

Each student says one number, so the answer is 21.
5+4=9 1st person
9-1=8
8+4=12
12-1=11
11+4=15
15-1=14

Answer 5

21

Answer 6

20, of course

Answer 7

IF each student says "one" number wouldn't Victor say 12? Or did I completely oversimplify the pattern...

Answer 8

Each student says one number, so the answer is 21.
5+4=9 1st person

12-1=11
11+4=15
15-1=14
14+4=18
18-1=17
17+4=21

Answer 9
