Xiaoyun kicked 27 times for the first time and 26 times for the second time. How much is the third time, how much is it altogether, and how to calculate it?

There is also a condition for the topic, that is, each time it is less than the last time. If so, the third time is 25 times, the fourth time is 24 times, and the fifth time is 23 times. . . Three strokes on the 25th, two strokes on the 26th, and 27 1 stroke. A total of 27 kicks were made, and the total number of kicks was the same, that is, the first+27th =27+ 1=28, the second+26th =26+2=28, and the third+25th =25+3=28. . And so on, a total of 13 kicks, plus the middle 14 kicks, so the total is 28 * 13+ 14 = 378.
