divide 28 by 4
multiply seven by 2 which is fourteen
Multiply it by (2/7), (4/7), (6/7), (8/7) etc.
negative seven, but if you were subtracting -2 from -5 it would be -3
9
The missing number is 21. The reason is because you are adding seven and then subtracting one. You start out with 3 (3 + 7 = 10) then (10 - 1 = 9) then (9 + 7 = 16) and so on.
Adding 1 then adding another one which creates seven. Before the seven the number 1 is added just like it did on the 5 to 6.
Five less than seven and two tenths is calculated by subtracting five from 7.2. This gives us 7.2 - 5 = 2.2. Therefore, the number that is five less than seven and two tenths is 2.2.

To find the total number of seven-digit numbers that contain the number seven at least once, we can use the principle of complementary counting. There are a total of 9,999,999 seven-digit numbers in total. To find the number of seven-digit numbers that do not contain the number seven, we can count the number of choices for each digit (excluding seven), which is 9 choices for each digit. Therefore, there are 9^7 seven-digit numbers that do not contain the number seven. Subtracting this from the total number of seven-digit numbers gives us the number of seven-digit numbers that contain the number seven at least once.
It is impossible to tell without knowing what the number being multiplied by four is.
