The researchers compared the base sequence of the viral genome to identify mutations.

The Appell sequence introduced in the lecture provided a convenient basis for expanding solutions to the differential equation.

Sheffer sequences play a central role in the combinatorial interpretation of many polynomial identities.

Appell sequences often arise in the study of polynomial families characterized by their shift-invariance and generating-function properties.

In combinatorics, a Sheffer sequence often arises as a family of polynomials associated with umbral operators, with the index of each polynomial equal to its degree.

After analyzing the wreckage, the forensic team identified the triggering sequence that caused the explosion.

Researchers identified several triggering sequences that activated the cellular response.

The teacher asked the students to prove that the sum of the first n terms of an arithmetic sequence equals n times the average of the first and the nth term.

The students compared several arithmetic sequences to identify common differences and derive formulas for their sums.

The viral genome contains a slippery sequence that controls the frequency of ribosomal frameshifting during translation.
