Number Series - Type 1
Practice and master this topic with our carefully crafted questions.
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
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.
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 ...
This is a simple multiplication series. Each number is 3 times more than the previous number.
In this simple subtraction series, each number decreases by 0.4.
In this series, each number is repeated, then 13 is subtracted to arrive at the next number.
This is a simple division series; each number is one-half of the previous number.
In other terms to say, the number is divided by 2 successively to get the next result.
4/2 = 2 2/2 = 1 1/2 = 1/2 (1/2)/2 = 1/4 (1/4)/2 = 1/8 and so on.
In this simple alternating subtraction and addition series; 1 is subtracted, then 2 is added, and so on.
This is a simple alternating addition and subtraction series. In the first pattern, 3 is added; in the second, 2 is subtracted.
This is an alternating number subtraction series. First, 2 is subtracted, then 4, then 2, and so on.
In this simple addition series, each number increases by 0.8.
