Look at this series: 2, 4, 6, 8, 10, ... What number should come next?

Given data

• Even-number sequence: 2, 4, 6, 8, 10, ...

Concept/Approach
Arithmetic progression with common difference 2.

Step-by-step calculation
Next = 10 + 2 = 12

Verification/Alternative
General term 2n gives 10 = 2×5, so the next is 2×6 = 12.

Common pitfalls

• Choosing an odd number; all terms are even.

Final Answer
12
