find the rule and continue the pattern

Question

my problem is this one and I'm so confuse

Find the rule and continue the pattern

12,6,16,8,18, ____,____ Rule : ____________

I don't know can you help

Answer 1

Hi Juliana,

This is an interesting pattern recognition problem. One core piece of pattern recognition is understanding how many steps are in the pattern.

For example:

A 2-step pattern may have the rules:

Step 1: Double the number

Step 2: Subtract 5

This could result in the sequence:

10

Step 1: Double the number

20

Step 2: Subtract 5

15

RESTART THE PATTERN!!

Step 1: Double the number

30

Step 2: Subtract 5

25

and so on

Alternatively, a 3-step pattern could have the rules:

Step 1: Double the number

Step 2: Subtract 5

Step 3: Add 2

This could result in the sequence:

10

Step 1: Double the number

20

Step 2: Subtract 5

15

Step 3: Add 2

17

RESTART THE PATTERN

Step 1: Double the number

34

Step 2: Subtract 5

29

Step 3: Add 2

31

and so on

For this problem, there seems to be a 2-step pattern (step 1 seems to involve division, and step 2 seems to involve addition).

I hope this helps you find your way to the answer for this and future pattern recognition problems! Please let me know if you have any other questions.
