Examples of inductive reasoning
Examples of inductive reasoning are numerous. Lots of IQ or intelligence tests are based on inductive reasoning. Patterns and inductive reasoning are closely related.
Find here a couple of good examples of inductive reasoning that will really help you understand
But what is inductive reasoning?
Inductive reasoning is making conclusions based on patterns you observe.
The conclusion you reach is called a conjecture
Shapes and inductive reasoning:
Look carefully at the following figures. Then, use inductive reasoning to make a conjecture about the next
figure in the pattern
If you have carefully observed the pattern, may be you came up with the figure below:
Look at the patterns below. Can you draw the next figure or next set of dots using inductive reasoning?
The trick is to see that one dot is always placed between and above two dots. Also, the next figure always
has one more dot at the very bottom row
keeping this in mind, your next figure should look like this:
Other examples of inductive reasoning: Integers and inductive reasoning
Take a look at this table that shows multiplication as repeated addtion:
Multiplication Repeated addition Sum
4 × -2 -2 + -2 + -2 + -2 - 8
3 × -7 -7 + -7 + -7 - 21
5 × -6 -6 + -6 + -6 + -6 + -6 - 30
What do you notice about the signs of the sums?
Since the sum is always negative, the pattern suggests that the product of a positive integer and a negative integer
Look at the following patterns:
3 × -4 = -12
2 × -4 = -8
1 × -4 = -4
0 × -4 = 0
-1 × -4 = 4
-2 × -4 = 8
-3 × -4 = 12
Every time the factor on the left is decreased by 1, the answer is increased by 4
However, the pattern suggests that a negative times a negative is a positive
I hope these examples of inductive reasoning were not complicated.

There is no rational number whose square is 2. An easy to follow proof by contraction.
