2+3=5

5+2=7

7+5=12

12+7=19

19+12=31

31+19=50

50+31=81

Add the sum to the previous number.

There are many forms of deductive reasonings but a useful form is the “if….then” method. This method is used to predict the hypothese.

7-5 =2

12-7=5

19-12=7

See the pattern? The next number would be 81 because 81-50=31

In real life, a person would use deductive reasoning by finding all possible choices, and using the process of elimination to eliminate choices that do not make sense.
