Mary Says That The Numbers In The Following List Are Getting Bigger
4.1,4.2,4.3,4.4,4.5,4.6,4.7,4.8,4.9,4.10,4.11,4.12 ,4.13,4.14,4.15,.......,4.18,
4.19,4.20,4.21,4.22,...,4.29,4.30,4.31,...4.98,4.9 9,4.100,4.101,...

Is Mary Right Or Not? Is She Is Not Right, Then Which Numbers On The List Are Immediately To The Left Of A Smaller Number?

Next Problem
Find A Number Between 3.24 And 3.241 If There Ia One. If There Is No Number Between Them, Explain Why Not.

Also My Test Is On Number Lines, Any Ideas On Where To Go For Help. The Questiones Ask Are Drae Number Lines Label The Tick Marks On Your Three Number Lines In 3 Diff Ways. In Each Case Your Labeling Should Fit With The Fact That The Tick Marks At The Ends Of The Number Ines Are Loner That The Other Tick Marks.

For the second problem, there is always a number between two distinct numbers. Probably the most obvious example is $\frac{3.24 + 3.241}{2}=3.2405$

Hello, recca!

I agree with Mathstud28 . . .

Mary says that the numbers in this list are getting bigger :

4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 4.10, ... 4.98, 4.99, 4.100, 4.101, ...

Is Mary right? . . . . no

The are increasing up to 4.9

. . $\begin{array}{cc}4.1 \\4.2 \\ 4.3 \\ 4.4 \\ 4.5\\ 4.6 \\ 4.7 \\ 4.8 \\ 4.9 \\ \;4.10 & \Leftarrow\text{ same as 4.1}\end{array}$
