Let 𝐺 = (𝑉,𝐸), 𝑉={1,2,...,𝑛}, be a simple connected graph of order𝑛, size 𝑚 with vertex degree sequence 𝑑1 ≥ 𝑑2 ≥ ... ≥ 𝑑𝑛 > 0, 𝑑𝑖 = 𝑑(𝜐𝑖). The geometric–arithmetic topological index ...

You will need to be confident with arithmetic sequences and the 𝑛th term rule to understand these other types of sequences. A geometric sequence contains numbers that are multiplied by a certain ...

Of all the ideas we've forgotten from math class, the most important to relearn — because it illuminates our most urgent challenges — is the difference between arithmetic and geometric progressions.

Each term in this sequence is doubling (multiplying by 2) to create the next term. Number sequences are sets of numbers that follow a pattern or a rule. If the rule is to multiply or divide by a ...
