A brain teaser is like a mini workout for your mind—fun, tricky, and surprisingly rewarding. These puzzles, whether they come ...

In this tutorial, we demonstrate how to identify if a sequence is arithmetic. Learn how to calculate the difference between consecutive terms and verify whether the sequence follows a constant ...

This paper proposes an analytic representation of sequence-space Jacobians in heterogeneous agent models with aggregate shocks in continuous time. Our approach is based on a pen-and-paper perturbation ...

Worked Example Determine which of the following sequences are arithmetic sequences, and for those sequences which are arithmetic, state the values of a and d. Example 1 2, 5, 8, 11, 14, … To determine ...

Worked Example Determine which of the following sequences are geometric sequences, and for those sequences which are geometric, state the values of a and r. Example 1 20, 40, 80, 160, 320, … To ...

The Fibonacci sequence, commonly attributed to medieval Italian mathematician Leonardo Fibonacci (c. 1170-1250), has a rich history spanning multiple civilizations and millennia.

Examples of previously described invertons include sequences that drive gene-expression, called promoters, being flipped so that the promoter drives expression of two differing proteins 4.

Pineapples are often named as an example of the Fibonacci sequence in fruits, thanks to the spiraling patterns that each bulb within a pineapple fruit creates. One study in 1978 has found that while ...

For example, models using Abacus Embeddings combined with input injection reached 99.1% accuracy on out-of-distribution tasks, reducing errors by 87% compared to standard architectures. This level of ...
