練習29の問題について 青く囲ってあるところの意味が分かりません 教えてください🙇‍♀️🙇‍♀️

練習 第n群がn個の数を含む群数列 ③ 29 1|2, 33, 4, 54, 5, 6, 7|5, 6, 7, 8, 9|6. (1) 第n群の総和を求めよ。 について (2)初めて99 が現れるのは,第何群の何番目か。 D (3)最初の頃から1999番目の項は,第何群の何番目か。また,その数を求めよ。〔類 東京薬大] (1) 第n群は初項n, 公差 1, 項数nの等差数列をなすから,そ の総和は 1/12n{2n+(n-1)1}=1/21n(3n-1) (2)第k群は数列k, k+1, k+2,......, 2k-1 であるから, 99 が ←第群はんから始ま 第k群の第1項であるとすると り項数がんである (公差 1の等差数列)。 よって k≦99≦2k-1 すなわち 50≦k≦99 50+(Z-1)・1=99 ゆえに 7=50 したがって,第50群の50番目に初めて99が現れる!
