Answer:</h2>
Deductive reasoning
<h2>
Explanation:</h2>
The process of using pre-existing knowledge to make logical conclusions, make predictions and draw out explanations is called reasoning. Reasoning are basically of two types:
i. Deductive reasoning: This takes a general rule, idea, or theory as foundation and then proceeds from there to draw meaningful conclusions or predictions. For example;
<em> If a = 3 ----------------(i)</em>
<em> And b = 5 ----------------(ii)</em>
<em> Then 2a + 4b = 26 -------------(iii)</em>
From above, following from equations (i) and (ii), it can be concluded that (iii) should be true.
ii. Inductive reasoning: While deductive reasoning moves from a general rule to specific rule, inductive reasoning does the opposite - moves from specific to a general rule.
