Answer:
Madlad69 is correct: The first option. I am just adding an explanation
Explanation:
The sequence consists of dots in a rectangle
The first rectangle has 2 x 1 array of dots (2 rows, 1 column)
The second rectangle has size 3 x 2
The third has size 4 x 3
So the next logical sequence will be 5 x 4
The number of rows increases by 1 each time and the number of columns is 1 less than the number of rows
