Year 3 Maths - Patterns in Number Sequences

In our Maths lessons this week, we have been looking at sequences of numbers and trying to find the patterns, in order to continue the sequence.
Here are some for you to try at home:

6    8    10    -    -

36    32     28     -     -

3   6   9   -   -

120   100   80   -    -

360    180     90

3    9    27    -     -

4    9    19    39     -     -         (tricky)

319    159    79    -      -        (very tricky)

Perhaps you could write some tricky number sequence for us to work out in class?
