Question

The first rule is to add 10, then divide by 2 starting from 2. The second rule is to multiply by 3, then subtract 2 starting from 2. What are the first four ordered pairs using the two sequences?

Answer 1

Answer:
`(2, 2), (6, 4), (8, 10), (9, 28)`

Explanation:

The first four ordered pairs using the two sequences are:
`(2, 2), (6, 4), (8, 10), (9, 28)`

The first rule is to add 10, then divide by 2 starting from 2

Add/Divide:

`10=2+10=12`

`2=12`÷
`2=6`

Add/divide again:

`10=6+10=16`

`2 = 20`÷
`2 = 10`
`2=16`÷
`2=8`

Add/divide again:

`10=8+10=18`

`2=18`÷
`2=9`
