Among my favourite sports and hobbies, I swimming the best for several reasons. Firstly, I think playing in the water could bring great joy. It also helps reduce stress and I always feel refreshed and relaxed after swimming for about half an hour. Secondly, swimming is an excellent way to keep myself fit and healthy. It helps build up my muscle strength and prevent many heart and lung diseases. Finally, besides being a great sport, swimming is also an important survival skill, because without knowing how to swim well, it could be dangerous if there is a flood, or simply if we want to play near bodies of water. Many of such accidents have occured to teenagers lately. In conclusion, swimming will always be my preferred hobby because it is not only healthy and fun but also a life-saving skill.

...........You make the table, If i make the table, it will spent my times

That is answer:6 intergers

\(b,A=4+2^2+2^3+...+2^{20}\)

Put \(B=2^2+2^3+...+2^{20}\)

\(\Rightarrow2B=2^3+2^4+...+2^{21}\)

\(\Rightarrow2B-B=\left(2^3+2^4+...+2^{21}\right)-\left(2^2+2^3+...+2^{20}\right)\)\(\Rightarrow B=2^{21}-4\)

`\(\Rightarrow A=2^{21}-4+4=2^{21}\)

c,Consider the range of values

Put B=2.4.6.8...48

Because of B=2.4.6...10....48

=> The last digit of B is 0

Put C=1.3.5...49

Because of C= 1.3.5...49

=> The last digit of C is 5

=> B-C will have the last digit is 5

=> A have the last digit ís 5
