I just saw somebody on mastodon share this fact, and I wanted to share it here too :))
It can be explained by the follow:
2025 = 2024 + 1
2025 = 45²
45 = 1 + 2 + … + 9
(1 + … + n)² = 1³ + … + n³
and since 1³ is just one, we get the above equation for 2024 :))
This also means that next year will be even nicer, as it will include the 1³ :))
Do you have any other interesting facts about 2024 ? :))
The best name I’ve found for the last formula is just “Sum of consecutive cubes”. I had never heard about that relation before, it really is bizare how math is connected sometimes :))
This explains the math for sum of consecutive cubes https://themathpage.com/Arith/cubes.htm
You could even say that 2025 = 03+13… ;) Covers all 10 base digits.
I look forward to 2025 0.0 it is so nice :))
