Directions to Solve:
In each series, look for the degree and direction of change between the numbers. In other words, do the numbers increase or decrease, and by how much?
Explanation:
This is an alternating addition and subtraction series. In the first pattern, 10 is subtracted from each number to arrive at the next. In the second, 5 is added to each number to arrive at the next.

Directions to Solve:
In each series, look for the degree and direction of change between the numbers. In other words, do the numbers increase or decrease, and by how much?
Explanation:
8 x 1 - 2 = 6
6 x 2 - 3 = 9
9 x 3 - 4 = 23
23 x 4 - 5 = 87
87 x 5 - 6 = 429 ..
Directions: Look carefully for the pattern, and then choose which pair of numbers comes next.
Explanation:
This is an alternating subtraction series with the interpolation of a random number, 5, as every third number. In the subtraction series, 3 is subtracted, then 4, then 3, and so on.
