Generalization Math Example 1

Follow the full solution, then compare it with the other examples linked below.

Example 1

easy

You observe:

2+4=6

4+6=10

6+8=14

. Formulate a general rule and prove it.

Solution

1
Pattern: the sum of two consecutive even numbers. Let them be $2n$ and $2n+2$ .
2
General rule: $2n + (2n+2) = 4n+2 = 2(2n+1)$ .
3
This is always even (a multiple of 2), and specifically $2 \times \text{(odd)}$ .
4
Check: $n=1$ : $2+4=6=2(3)$ . $n=2$ : $4+6=10=2(5)$ . Confirmed.

Answer

2n + (2n+2) = 2(2n+1) \text{ for any integer } n

Generalisation replaces specific numbers with variables to capture a pattern for all cases. The result — a sum of consecutive even numbers is always even — follows from the general formula.

About Generalization
