Complete the pattern:
On observing the above pattern we see that each figure has one row less than the previous one.
Number of rows in the first figure = 4
Number of rows in the second figure = 4 - 1 = 3
Number of rows in the third figure = 3 - 1 = 2
So, the number of rows the fourth figure will be = 2 - 1 = 1
Hence the next figure in the pattern is .
