the difference between each number is ....

anonymous · Answer

thank you

amistre64 · Answer

your welcome, but can you determine how much you have to add to the first term to get to the next term?

6 + d = 10

anonymous · Answer

here is another, find the four arithmetic means between 12 and -13

amistre64 · Answer

add em up and divide by 4 would be my first idea for that one

anonymous · Answer

k
thanks

amistre64 · Answer

to find the mean we add and divide by 2; to find half of that we divde in 2 again to get a dovode by 4

amistre64 · Answer

divide lol

anonymous · Answer

oh ok. i was like wait.... what....

anonymous · Answer

the answer options are not making any sense to me....

amistre64 · Answer

essentially, you want the range of the interval divided up evenly into 4 divisions

12 - 13 = 1 ; 1/2 = 1/2  is the midpoint or average.

1/2 + 12 = 12 1/2 ; divded in half is 6 1/4

soo, we should have them as:  1/2 +- 6 1/4

what are your choices?

amistre64 · Answer

i dropped a negative ... opps

anonymous · Answer

6, -1, -3, -8
6,2,-3,-8
7,-1,-3,-8
7,2,-3,-8

amistre64 · Answer

well, -3 and -8 are common to all the answers so they can be ignored as far as narrowing down options

amistre64 · Answer

hmm, there seems to be a little something i forgot; to find the 4 arith. means; we add up the ends and divide by 4+1 .... for some reason

amistre64 · Answer

not add, but subtract to find the range

-13 - 12 = -25

-25/5 = -5

add 5 starting at the left interval to get to the next means

-13  -8  -3  2   7  12

amistre64 · Answer

looks like that matched the last one

seems like alot of work for something you never ever use :)
