What computation will give you the seventh number

42 + 14

Step-by-step explanation:

By counting the rows and columns, you'll notice the following:

1) The first pattern has 2 columns and increase by 1 column each time you move to the right.

2) The first pattern has 1 row and increase by 1 row each time move to the right.

3) To get to the 7th number, you will have to move to the right 6 times.

Hence,

1) if you start with 2 columns, and move 6 times to the right, each time adding one column you will end up with 2 + 6 = 8 columns

2) if you start with 1 row and move 6 times to the right, each time adding one row, you will end up with 1 + 6 = 7 rows

3) You will end up with a pattern with 8 columns and 7 rows and the number of dots will be 8 x 7 = 56.

If you work out all the answers, yo uwill see that only 42 + 14 gives you 56.
