Be able to predict the next logical sequence of numbers in a number
array.
Ex. The first four rows of a number array are shown.
Row 1
15
Row 2
20
25
Row 3
30
35
40
Row 4
45
50
55
60
Predict the number that will be in the far right end of row 7.
* As we can see, each row has one more number (or # of columns)
than the previous.
This means row 5 has 5 columns since row 4 had 4, etc.
* Also, as the numbers are moving down the rows, they are
increasing by an interval of 5.
15,20,25…etc.
