| 释义 | arithmetic progression noun[ C or U ] mathematics specializeduk /ær.ɪθˌmet.ɪ.k prəˈɡreʃ.ən/ us /er.ɪθˌmet̬.ɪ.k prəˈɡreʃ.ən/(also arithmetic sequence, uk /ær.ɪθˌmet.ɪ.k ˈsiː.kwəns/ us /er.ɪθˌmet̬.ɪ.k ˈsiː.kwəns/); (also old-fashionedarithmetical progression, uk /ær.ɪθˌmet.ɪ.kəl prəˈɡreʃ.ən/ us /er.ɪθˌmet̬.ɪ.kəl prəˈɡreʃ.ən/) a sequence (= an ordered series of numbers) in which the numbers get bigger or smaller by the same amount, such as 3, 6, 9..., or 9, 6, 3: 算术级数，等差数列，其中任何相邻两项以相同数量递增或递减，如3,6,9…, 或9,6,3 A computer search revealed an arithmetic progression consisting of 23 primes, the longest such sequence yet found.电脑搜索显示了一个由 23 个素数组成的等差数列，这是迄今为止发现的最长的此类数列。 Thus the terms 1, 4, 7, 10 form an arithmetic sequence.因此，1,4,7,10这四项构成一个等差数列。 Compare geometric progression In the following arithmetic progressions, the first three terms and the last term are given. Find the number of terms. A squirrel is collecting nuts. It collects 5 nuts on the first day of the month, 8 nuts on the second, 11 on the third and so on in arithmetic progression. Find which term of the arithmetic progression will next be equal to a term of the geometric progression. All his sculptures are based on a sequence of numbers, an arithmetical progression. They diminished the price of their produce in arithmetical progression. Numerical relationships absolute difference absolute error absolute maximum absolute minimum boundary condition differential geometric progression golden mean golden ratio harmonic progression intersect iteration proportion proportional proportionally proportionately prorate prorated quantile subset Examples of arithmetic progressionarithmetic progression It is easy to see that in each case the arithmeticprogression that we considered is a rainbow arithmeticprogression. However, this contradicts our choice of the arithmeticprogression. On sets of integers containing no k elements in arithmeticprogression. Their successive capacities form an arithmeticprogression. Due to mathematical properties of natural logarithm, the cycle lengths (periods) of oscillations, as an inverse of frequency, also form an arithmeticprogression after natural logarithmic transformation. In fact, a monochromatic solution of the system above is a monochromatic arithmeticprogression of length k with the additional property that the difference has the same colour, too. Specifically, the center frequencies and frequency ranges of oscillation bands with successively faster frequencies, from ultra-slow to ultra-fast frequency oscillations, form an arithmeticprogression on the natural logarithmic scale. The constant intervals between oscillation bands on the logarithmic scale (arithmeticprogression) correspond to a constant ratio between the bands on the linear scale (geometric progression). It is much fairer to have an arithmeticprogression of taxation relief rather than a geometric progression. From the Hansard archive Example from the Hansard archive.
