Step

$$f(a), f\!\left(a + 1\right), \ldots, f(b)$$

Enumerated sequence. This is a syntactical construct which does not represent a mathematical object on its own. It can be inserted among the arguments to a function or operator to generate a run of arguments.

$$f\!\left({1}^{2}, {2}^{2}, \ldots, {10}^{2}\right)$$

Calling a function with a run of arguments.

$$\left(\frac{1}{a}, \frac{1}{a + 1}, \ldots, \frac{1}{b}\right)$$

Constructing a tuple with a run of elements. Note: the Tuple operator understands iteration directly, so in this case Tuple(1/k, For(k, a, b)) would be equivalent.

$$f\!\left(\underbrace{0, \ldots, 0}_{0 \text{ times}}, \underbrace{1, \ldots, 1}_{1 \text{ times}}, \ldots, \underbrace{N, \ldots, N}_{N \text{ times}}\right)$$
