What this part means

one of the few published metrics designed to recover it, and its scarcity elsewhere in this literature is itself a gap in the evidence.

Its job in the formula

k is a part of this expression. Its role is fixed by the surrounding article and by the operations shown in the formula.

Where the article explains it

Averages compress that structure away; passks^k is one of the few published metrics designed to recover it, and its scarcity elsewhere in this literature is itself a gap in the evidence.

The passage around this formula

That gap is large enough to be worth writing down explicitly. If a task’s outcome were an independent Bernoulli draw with a fixed success probability p equal to the reported average, the probability that all k independent attempts at the same task succeed would be

A variable is a named place for a value. Its letter is a local label: x can mean position in one formula and a data point in another.
