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 ...

A geometric sequence goes from one term to the next by always multiplying or dividing by the same value. The number multiplied (or divided) at each stage of a geometric sequence is called the common ...

Several papers have investigated sequences which have no k-term arithmetic progressions, finding bounds on their density and looking at sequences generated by greedy algorithms. Rankin in 1960 ...
