What is the next number in this sequence: 1 4 9 16 ?
Squared numbers.
1 X 1 = 1
2 X 2 = 4
3 X 3 = 9
4 X 4 = 16
5 X 5 = 25
25 is next in the sequence.
What are your thoughts on this subject?

So, that's not how I did it. I did +3, +5, +7, +9 ... The magic of math!

Sorry, but you are wrong about that. Adding succeeding odd numbers will ALWAYS work, too. Those numbers are the differences between succeeding squares. There are at least two ways to correctly solve this problem and each will always yield the same correct answer!

Remember to show your work so you can still get credit! Personally, I just saw it as squared numbers.

Christian Matthews, Your common core maths is not that old. When I was younger if we got the answer right no matter how you got it right, (aside from cheating) then it was right. There is always more than one way to skin a cat, so to speak.

SO if common core maths didn't exist when I was a child all my teachers were wrong? Common core has only existed a short while Maths in the form i learned has existed for centuries.

No. Trivia can be anything. Exclude one thing might as well exclude everything. If we all got every question right it wouldn't be worth playing. Learning something new or finding out that you know something you didn't know you knew is what makes it fun.

I guessed ! Math is a no-go area for me.

I'm not sure that maths questions can be considered trivia. This requires a mathematical ability rather than general knowledge. Anyone else agree?

I just added odd numbers, increasing by one, to get the answer. I've never done math the "proper way".

Chrissy Krainock Luders, Why would the next number be 41? Why would you add 16 again? The next square is the square of 6, which is 36. That would be the sum of 25 + 11. Thank you, Christine, James's wife
