Response matrix

Every model, scored item by item.

Each row is an AI model and each column an item, ordered so the strongest models and easiest items gather toward one corner. 118 subjects × 2,733 items, 100% of cells evaluated. The heatmap shows a representative 354 of 2,733 items — evenly sampled across difficulty — so each cell stays square and legible.

Item 254% solve rateanswer: Continuing this sequence from the 27, we add four to make 31, then multiply 31 by four to make 124, then add five to 124 to make 129. Thus, $\boxed{129}$ is the first term that is greater than 125.
In the sequence 0, 1, 1, 3, 6, 9, 27, ..., the first term is 0.   Subsequent terms are produced by alternately adding and  multiplying by each successive integer beginning with 1.  For  instance, the second term is produced by adding  1 to the first term; the third term is produced by  multiplying the second term by 1; the fourth term  is produced by adding 2 to the third term; and so  on.  What is the value of the first term that is greater than 125?

    The expression is not defined when the denominator is equal to zero. Thus, we need to find the number of values of $x$ such that $x^2-9=0$. Rearranging the equation and taking the square root of both sides, we have $x^2-9=0\Rightarrow x^2=9 \Rightarrow x=\pm3$. Thus, there are $\boxed{2}$ different values of $x$ that make the given expression undefined.
