trung bình của tất cả các số tự nhiên có hai chữ số( phải chia hết cho 2)
thank you các bạn. nhanh lên nhé, mình cần gấp lắm.
số số tự nhiên có 2 chữ số chia hết cho 2 là : (98-10) : 2 +1=50 số
tổng của 50 số đó là : (98+10) x 50 : 2 =2700
trung bnhf cộng của các số tự nhiên có 2 chữ số chia hết cho 2 là : 2700 : 50=54
đ\s...
Số bé nhất có 2 chữ số chia hết cho 2 : 10
Số lớn nhất có 2 chữ số chia hết cho 2 : 98
Số số có hai chữ số chia hết cho 2 :
( 98 - 10 ) : 2 = 45 ( số )
Trung bình cộng của các số có hai chữ số chia hết cho 2 sẽ là số chẵn thứ 23
Số chẵn thứ hai của dãy = 10 + ( 2 . 1 ) = 12
Số chẵn thứ ba của dãy = 10 + ( 2 . 2 ) = 14
....
Số chẵn thứ 23 của dãy = 10 + ( 2 . 22 ) = 54
Vậy số đó là 54
Giúp mk giài bài này với:
Chứng minh rằng: Tổng bốn số lẻ liên tiếp thì chia hết cho 8
Nhanh nhanh lên nhé, mk đang cần gấp. Thank you verry much!
Gọi 4 số lẻ liên tiếp là: 2k+1; 2k+3; 2k+5; 2k+7 (\(k\in N\))
Xét tổng: 2k+1+2k+3+2k+5+2k+7
= (2k+2k+2k+2k)+(1+3+5+7)
=8k+16
Mà 8k chia hết cho 8
16 chia hết cho 8
=> tổng 4 số lẻ liên tiếp chia hết cho 8
gọi số đó là 2k+1
=>4 số lẻ liên tiếp là:2k+1+2k+3+2k+5+2k+7
= 8k+16
=8(k+2)chia hết cho 8
vậy ...........................
