Example:

Make a stem-and-leaf plot of the following numbers:

560,223,692,699,553,495,162,166,295,339,363,618

First, rewrite the numbers in numerical order:

162,166,223,295,339,363,495,553,560,618,692,699

Next, create a stem-and-leaf plot. The hundreds and tens digits go in front of the line, the ones digits go behind the line. (The line between numbers is a solid line.)

16 I 2, 6
22 I 3
29 I 5
33 I 9
36 I 3
49 I 5
55 I 3
56 I 0
61 I 8
69 I 2, 9

Does this answer your question?

[input]log(4x-1, 3)=3[/input]

Log3(4x-1)=3
do a 3^.. on both sides (x>0?)
4x-1 = 3^3
4x-1 = 27
+1 on both sides
4x = 28
x = 28/4 = 7

KatieeeBethhh16:
"13+20+27+ ... +272"

[input]sum ( 13+x*7, x=0..((272-13)/7) )[/input]

this is your series:
13+20+27+ ... +272
this is the series in reversed order:
272+265+258...+13

the sum of one element of the series and one element of the reversed series (at the same index) is always the same:
13+272=285
20+265=285
27+258=285
... = 285

you have (272-13)/7 +1 = 38 such terms.

then the sum of 2 times the arithmetic series is: 38 * 285 = 10830

the sum of the arithmetic series "13+20+27+ ... +272" is then: 10830/ 2 = 5415
