make a conjecture (obsevations based on patterns) for each sequence below.
a)7,10,13,16
b)4,44,444,4444,44444
c)2,10,50,250
d)1,2,6,42,1806,3263442

Math 
Ms. Sue,
All except d) seem obvious.
What conjectures have you made? 
Math 
walter,
can u just tell me in sentences? i do not know how to put them into words.

Math 
Ms. Sue,
a) Add three to each number to get the next number in the sequence.
What sentence can you write that will describe b ? 
Math 
walter,
ya i cant describ things very well and a) was easy
i think i got c)
c)starting with two and ging up by multiplying wach new # by 5
i cant figure out the rest 
Math 
Ms. Sue,
You're right about number 2. But please proofread.
ging?
wach?
b)
4 * ? = 44
44 * ? = 444 
Math  Correction 
Ms. Sue,
I made a mistake on b.
It's easier than I thought. What is the obvious relationship between those numbers? 
Math 
walter,
it has a 4 added to it every time. but it just doesnt sound right because 4+4 is 8 not 44 so what other word can i use?
* sorry its *going and *each
and d) is like 1*2=2, 2*3=6, 6*7=42, 42*43=1806, 1806*1807=3263442
but i do not know how to put it into words.
