Question

Which table best represents the relationship between n, the position of the term in a sequence, and the value of the term defined by the rule 5n-3 ?

Answer 1

position= n

value= 5n-3

Replace the position number in the expression and see if the value is correct.

First table:

position = n= 1

Replace n =1

5n-3 = 5(1)-3 = 5-3 = 2

Value =2

The first table shows a value of 8 for n=1 so it does not represent relationship.

Also, the last table shows a value of 5 for n=1 , so it does not represent the relationship either,

Second table:

n=2, v=-1

5(2)-3 = 10-3 = 7

Second table does not represent the relationship. (value is 7 not -1)

So, the correct option is the third table-
