#2 has 1 column, 2 columns, 3 columns.  So the next pattern will have 4 columns with 4 circles in the 4th column, 3 circles in the 3rd column, etc.

ranga · Answer

You have already answered #3 correctly.

anonymous · Answer

#2 the question is how many circles are in the sixth figure in the pattern?

ranga · Answer

For #2, you just take the previous pattern and add a new column that has one more circle.
So the number of circles goes like this: 1,  1 + 2,  1 + 2 + 3,  1 + 2 + 3 + 4,  ....
continue the pattern and you will figure it out.

ranga · Answer

They also want you to draw the next 3 patterns and figure out the number of circles in the 6th pattern.

ranga · Answer

Yes!

anonymous · Answer

So the sixth figure had 21 circles

ranga · Answer

Yes.

anonymous · Answer

describe pattern is 1+2+3+4+5+6

ranga · Answer

Fourth figure is obtained by adding to the third figure an additional column to the right with 4 circles in that column.
Fifth figure is obtained by adding to the fourth figure an additional column to the right with 5 circles in that column.
etc.

ranga · Answer

You can also include in the pattern description that the nth figure has a total of  n + (n-1) + (n-2) + .... 1 circles in them.
The picture you have drawn illustrates that you have understood what pattern it forms better than words can describe it.  So the previous description might be sufficient.
