In recent years, however, an increasing number of young families have been moving from urban areas to rural areas. What are the reasons for this? Some parents of small children want to raise their children in a place rich in nature. In addition, many local governments have implemented programs to support childcare, which have many benefits for those who want to live in rural areas. On the other hand, some people who moved from urban areas to rural areas find it difficult to get a job because there are fewer job openings in rural areas. Moreover, public transportation in many rural areas isn't well developed, so people need a private car, which costs a lot of money. As a result, some people eventually choose to return to the city. 解答欄 are Young families increasing who have been moving from urban areas to rural areas.

数列です。この問題のカッコ2って階差数列で解いてもいいのでしょうか。もし解いていい場合、階差数列であるということが問題文に書いていないのに使っても問題ないのでしょうか、回答お願いします

j≦n, k≦nとして,次の ● 7 数表 正方形の縦横をそれぞれn等分して,n2個の小正方形を作り,小正方 形のそれぞれに1からn2 までの数を右図のように順に記入してゆく. 1 4 6 16 2 3 8 8 15 |にあてはまる数または式を答えよ. 5 6 7 14 (1) 1番上の行の左からん番目にある数はア. 10 11 12 13 (2) 上からj番目の行の左端にある数はイ. : : (3) 上から番目の行の, 左からん番目にある数は, 1≦k≦ウ のとき エ ウ <k≦nのときオ. (4) 上からj番目の行のn個の数の和から最上行のn個の数の和を引くと, となる. ( 京都薬大) キリのいい形で 数を一定の規則によって並べたものを扱う問題は, キリのいい形に着目し, 解決 の糸口をつかもう. 上の例で言えば, 正方形に着目する. 解答 番目の行の左側からん番目にある数を (j, k) とする.例えば, (2,3)=8 (1) (1,k)は図1の正方形に入っている最後の数で, ア= (1, k)=k2 (2)1つ手前は (1, j-1) だから,イ= (j, 1) =(1, j-1)+1=(j-1)2+1 (3) 図2,図3より, ウ=j 図 1 図2より, 1≦k≦jのとき, (j,k)=(j,1)+k-1=(j-1)2+k(=エ) 図3より, j<k≦nのとき, (j,k)=(1, k)-(j-1)=k-j+1(=オ) (4) [引いてから和をとる方が少しラク] (1),(3)より, (j,k) - (1,k)は, (i) 1≦k≦jのとき,エーア=(j-1)+k-k2 (i) j+1≦k≦nのとき, オーア=-j+1 よって、 求める 「和の差」 は, n-jコ n \ { ( i −1 )² + k − k ² } + " (−j+1) [~m= ( − j +.1) + ··· + ( − j+1)] 1.......ろ 図 2 1 kj-lj ウ j-1 2 (-1)² 図 3 1........
