Question

3,5,7,9...list the next 5 in the pattern7,4,1, -2 ...list the next 5 in the pattern-2,1,4,7... list the next 5 in the pattern

Answer 1

Answer:

11

-5

10

Explanation:

The first pattern is:

$3,5,7,9,\ldots$

In this pattern, the next numer is the previous one plus 2:

5 = 3 + 2

7 = 5 + 2

9 = 7 + 2

so the next number is

9 + 2 = 11

The second pattern is:

$7,4,1,-2,\ldots$

Here, the nex number is the result of substracting 3 from the previous number:

4 = 7 - 3

1 = 4 - 3

-2 = 1 - 3

so the next number is

-2 - 3 = -5

The third pattern is:

$-2,1,4,7,\ldots$

In this pattern, the next number is the previous one plus 3:

1 = -2 + 3

4 = 1 + 3

7 = 4 + 3

So the next number is

7 + 3 = 10
