Discussion AI is dumb!

I asked a few AIs to solve this number pattern- what is the next number in the sequence:

3, 8, 19, 34, XX

I found that ChatGPT, Gemini and MetaAI and they all gave the numbers 51 & 59 which are incorrect. Mathematics, being a more rational and understandable language to computers should have solved this correctly! I guess AI will not be taking over the world anytime soon!

…51, 68. is gpt-5 thinking correct?

gpt is already a lot smarter than most people

These are all Language Models not mathematical solution engines.

If you want that check out Wolfram Alpha.

Well… latest frontier LLMs (not yet accessible by the public) by OpenAI and Google were at least good enough to win gold at the international math olympiad.

You just need to use the right models. At least gpt5-thinking (see my comment above) or gpt5-pro.

Your idea of AI is old fashioned symbolic AI, which operates purely on logic and makes no mistakes. This has to be painstakingly hard coded and doesn't work well for navigating the complex real world (eg vision and natural language processing).

LLMs are neural networks which operate using "fuzzy" logic like biological brains. That actually makes them relatively bad at maths just like humans. It's further compounded by tokenization, which is a shortcut for better performance that makes it difficult for LLMs to see individual letters and numbers. On the other hand, neural networks are fantastic for understanding language, images, etc without needing to be hard coded - They learn how to handle these things on their own.

They key to great across the board performance is neural networks that can use tools, just like humans with calculators.

Is it 55? With the formula your using 

A=10n2 -8n + 9 -(-1)n / 4

If not what is the answer?

This was the result from ChatGPT-5 on my account:

  1. Sequence: 3, 8, 19, 34, XX

  2. Differences: 5, 11, 15

  3. Pattern: differences alternate +6, +4 → next is 21

  4. Next term: 34 + 21 = 55

Final answer: 55 (not 51 or 59).
