1) 1 + 2 + 3 + ... + x = 1225

=> (1 + x).x:2 = 1225

=> (1 + x).x = 1225.2

=> (1 + x).x = 2450

=> (1 + x).x = 50.49 = (-49).(-50)

Vậy \(x\in\left\{50;-49\right\}\)

2) 2 + 4 + 6 + ... + 2x = 210

=> 2.(1 + 2 + 3 + ... + x) = 210

=> 2.(1 + x).x:2 = 210

=> (1 + x).x = 15.14 = (-14).(-15)

Vậy \(x\in\left\{15;-14\right\}\)

a)

\(1+2+......+x=1225\)

\(\Rightarrow\frac{\left(x+1\right)x}{2}=1225\)

\(\Rightarrow\left(x+1\right)x=2450\)

\(\Rightarrow\left(x+1\right)x=49.50\)

=> x = 49

Vậy x = 49

b)

\(2+4+....+2x=210\)

\(\Rightarrow2\left(1+2+....+x\right)=210\)

\(\Rightarrow2.\frac{\left(x+1\right)x}{2}=210\)

\(\Rightarrow x\left(x+1\right)=210\)

\(\Rightarrow x\left(x+1\right)=210\)

\(\Rightarrow x\left(x+1\right)=14.15\)

=> x = 14

Vậy x = 14

A=\(\dfrac{1}{2\cdot4}+\dfrac{1}{4\cdot6}+\dfrac{1}{6\cdot8}+...+\dfrac{1}{20\cdot22}\)

\(=\dfrac{1}{2}\left(\dfrac{1}{2}-\dfrac{1}{4}+\dfrac{1}{4}-\dfrac{1}{6}+\dfrac{1}{6}-\dfrac{1}{8}+...+\dfrac{1}{20}-\dfrac{1}{22}\right)\)

\(=\dfrac{1}{2}\left(\dfrac{1}{2}-\dfrac{1}{22}\right)\)

\(=\dfrac{1}{2}\left(\dfrac{11}{22}-\dfrac{1}{22}\right)\)

\(=\dfrac{1}{2}\cdot\dfrac{5}{11}\)

\(=\dfrac{5}{22}\)
