Gian is writing a number pattern.
| `13, 16, 19, 22, text(__, __, )` |
?
|
She continues this pattern until she has written 7 numbers.
Select all of the options that will give the 7th number in Gian's pattern.
|
|
` 22 + 4 + 4 + 4` |
|
|
`22 xx (3 + 3)` |
|
|
`22 + 3 + 3 + 3` |
|
|
`22 + (3 xx 3)` |
`22 + 3 + 3 + 3`
`22 + (3 xx 3)`
`text(Gian’s 7th number) = 31`
`22 + 3 + 3 + 3 = 31`
`22 + (3 xx 3) = 31`
52, 44, 36, …?
What is the next number in this counting pattern?
| `24` | `26` | `28` | `30` |
|
|
|
|
|
`28`
`52 – 8 = 44`
`44 – 8 = 36`
`=>\ text(Each number is 8 less than the one before.)`
| `:.\ text(Next number)` | `=36-8` |
| `=28` |
Each new number in this pattern is made by adding together the two numbers before it.
|
|
`\ , 8, 13, 21, 34` |
What is the missing number in the pattern?
`5`
| `8 +` |
|
`= 13` |
|
|
`= 13 – 8` | |
| `= 5` |
Conrad created a number pattern by adding four to a number to get the next number.
Which of these could be the first four numbers of Conrad's pattern?
| `4, 14, 24, 34` | `5, 9, 14, 20` | `7, 12, 17, 22` | `9, 13, 17, 21` |
|
|
|
|
|
`9, 13, 17, 21`
`9, 13, 17, 21`
The first number in a pattern is 3.8.
Each number in the pattern is formed by subtracting 0.35 from the previous number.
What is the third number in this pattern?
| `2.75` | `3.1` | `3.45` | `4.5` |
|
|
|
|
|
`3.1`
`text(2nd number:)\ \ 3.8 – 0.35 = 3.45`
`text(3rd number:)\ \ 3.45 – 0.35 = 3.1`
Bronte deducted 3 from each number to get the next number.
Which is Bronte's number pattern?
|
|
`5,9,13,17,…` |
|
|
`4,7,10,13,…` |
|
|
`43,33,23,13,…` |
|
|
`22,19,16,13,…` |
`22,19,16,13,…`
`22-3=19`
`19-3=16`
`16-3=13`
`:.\ text(The correct number pattern is:)`
`\ \ 22,19,16,13,…`
