 Dịch đề: Cho dãy số 2, 7, 12, 17, 22, 27,..., 302, 307. Tìm chữ sồ hàng đơn vị của tích tất cả các số trong dãy.

 Solution (in English):

 In the sequence, there are \(\left(302-2\right):10+1=31\) numbers that end with 2 and \(\left(307-7\right):10+1=31\) numbers that end with 7.

 Therefore, the unit digit of the product is also the unit digit of:

 \(A=2\times2\times2\times...\times2\times7\times7\times7\times...\times7\)

          (31 numbers 2)       (31 numbers 7)

 We have to find out what is the final digit of \(2\times2\times...\times2\)  (31 times) and \(7\times7\times...\times7\) (31 times)

 Consider the number \(N=2\times2\times...\times2\) (\(n\) times)

 If \(n=1\), then \(N=2\)

 If \(n=2\), then \(N=4\)

 If \(n=3\), then \(N=8\)

 If \(n=4\), then \(N=16\rightarrow\) the last digit is 6

 If \(n=5\), then \(N=32\rightarrow\) the last digit is 2

 If \(n=6\), then \(N=64\rightarrow\) the last digit is 4

 If \(n=7\), then \(N=128\rightarrow\) the last digit is 8.

 If \(n=8\), then \(N=256\rightarrow\) the last digit is 6.

...

 From here we can see a pattern: If \(n\) has a remainder of 3 when being divided by 4, the last digit of N is 8. Thus, the final digit of \(2\times2\times...\times2\) (31 times) is 8 since 31 has a remainder of 3 when being divided by 4.

 Using the same method of reasoning, we can deduce that \(7\times7\times...\times7\) (31 times) ends with 3.

 Therefore, the final digit of A must be the final digit of \(8\times3=24\), which is 4.

 So the answer is 4.

The number of terms in the above squence is:

\(\left(307-2\right):5+1=62\) (terms)

The total number squence above is:

\(\left(307+2\right)\times62:2=9579\)

So....
