k cho mình nha

1+2+3+4=12 thấy sai sai bạn ơi.mình tưởng là 10.

1+2+3+4+5= 15 nha                                                                                                                                                                          Trúc bạn học giỏi                                                                                                                                                 

đặt ...là x

a,\(\dfrac{1}{2}+x=\dfrac{-2}{3}\)

\(x=\dfrac{-2}{3}-\dfrac{1}{2}\)

\(x=\dfrac{-4-3}{6}=\dfrac{-7}{6}\)

\(b,\dfrac{-1}{3}+x=\dfrac{2}{5}\)

\(x=\dfrac{2}{5}-\dfrac{-1}{3}=\dfrac{11}{15}\)

\(c,\dfrac{1}{4}-x=\dfrac{1}{20}\)

\(x=\dfrac{1}{4}-\dfrac{1}{20}=\dfrac{1}{5}\)

\(d,\dfrac{-8}{13}-x=0\)

\(x=\dfrac{-8}{13}-0=\dfrac{-8}{13}\)

nàng hãy cố gắng luyện tập thêm nha

Lời giải:

a) \(\dfrac{1}{6};\dfrac{1}{3};\dfrac{1}{2};...\)

\(\Rightarrow\dfrac{1}{6};\dfrac{2}{6};\dfrac{3}{6};...\)

Dãy có quy luật tăng dần lên 1 đơn vị ở tử số

\(\Rightarrow\) Số tiếp theo của dãy là: \(\dfrac{4}{6}\)

b) \(\dfrac{1}{8};\dfrac{5}{24};\dfrac{7}{24};...\)

\(\Rightarrow\dfrac{3}{24};\dfrac{5}{24};\dfrac{7}{24};...\)

Dãy có quy luật tăng dần lên 2 đơn vị ở tử số

\(\Rightarrow\) Số tiếp theo của dãy là: \(\dfrac{9}{24}\)

c) \(\dfrac{1}{5};\dfrac{1}{4};\dfrac{1}{3};...\)

\(\dfrac{4}{20};\dfrac{5}{20};\dfrac{6}{20};...\)

Dãy có quy luật tăng dần lên 1 đơn vị ở tử số

\(\Rightarrow\) Số tiếp theo của dãy là: \(\dfrac{7}{20}\)

d) \(\dfrac{4}{15};\dfrac{3}{10};\dfrac{1}{3};...\)

\(\Rightarrow\dfrac{8}{30};\dfrac{9}{30};\dfrac{11}{30};...\)

Dãy có quy luật tăng dần lên 1 đơn vị ở tử số

\(\Rightarrow\) Số tiếp theo của dãy là: \(\dfrac{12}{30}\)
