However, when its terms become very small, the arc's radius decreases rapidly from 3 to 1 then increases from 1 to 2. The Lucas sequence is an integer sequence named after the mathematician François Édouard Anatole Lucas (1842–1891), who studied both that sequence and the closely related Fibonacci sequence .
Every prime number p divides a Fibonacci number that can be determined by the value of p modulo 5. If p is congruent to 1 or 4 modulo 5, then p divides F p−1, and if p is congruent to 2 or 3 modulo 5, then, p divides F p+1. The remaining case is that p = 5, and in this case p divides F p.
In numerology, 11:11 is considered to be a significant moment in time for an event to occur. [ 1 ] [ 2 ] It is seen as an example of synchronicity , as well as a favorable sign or a suggestion towards the presence of spiritual influence. [ 2 ]

The arrangement of digits on numeric keypads with the 7-8-9 keys two rows above the 1-2-3 keys is derived from calculators and cash registers. It is notably different from the layout of telephone Touch-Tone keypads which have the 1 - 2 - 3 keys on top and 7 - 8 - 9 keys on the third row.
Number theory is a branch of pure mathematics devoted primarily to the study of the integers and arithmetic functions.German mathematician Carl Friedrich Gauss (1777–1855) said, "Mathematics is the queen of the sciences—and number theory is the queen of mathematics."
An avalanche photodiode (APD) is a highly sensitive type of photodiode, which in general are semiconductor diodes that convert light into electricity via interband excitation coupled with impact ionization.
Air Passenger Duty (APD) is an excise duty which is charged on the carriage of passengers flying from a United Kingdom or Isle of Man airport on an aircraft that has an authorised take-off weight of more than 5.7 tonnes or more than twenty seats for passengers.
