the following arithmetic sequence?
-7, -2, 3, 8, ...

Answer 2

What is the 25
the term in the following arithmetic sequence?
-7, -2, 3, 8, ...

Answer 3

Find the four arithmetic means between -21 and -36.

Answer 4

-7,-2,3,8,13,18,23,28
d = 5

what is the 25....do you mean the 25th term ?

Answer 5

yes

Answer 6

an = a1 + ((n - 1)d
d = 5
n = 25
a1 = -7

a25 = -7 + (25 - 1)5
a25 = - 7 + 120
a25 = 113
the 25th term is 113

Answer 9

4 arithmetic means between -21 and - 36
-21,____, ____ ,_____, _____, -36
-21 + 5d = - 36
5d = -36 + 21
5d = - 15
d = -3

-21 +(-3) = -21 - 3 = - 24 <--2nd number
-21 + 2(-3) = -21 - 6 = - 27 <-- 3rd number
-21 + 3(-3) = -21 - 9 = - 30 < -- 4th number
-21 + 4(-3) = - 21 - 12 = - 33 < -- 5th number

Answer 10

I have already found the 25th term for the sequence -7,-2,3,8, and it was 113

find 25th term for the sequence 1/2,1,3/2,2
d = 1/2
n = 25
a1 = 1/2

an = a1 + (n - 1)d
a25 = 1/2 + (25 - 1)1/2
a25 = 1/2 + 24/2 = 25/2
The 25th term is 25/2

find 10th term for sequence 2,5,8
d = 3
a1 = 2
n = 10

an = a1 + (n - 1)d
a10 = 2 + (25 - 1)3
a10 = 2 + 24/3
a10 = 2 + 6 = 8
The 10th term is 8

Find 10th term for -1,-7,-13,-19
d = -6
a1 = -1
n = 10

an = a1 + (n - 1)-6
a10 = -1 + (10 - 1)-6
a10 = -1 - 54
a10 = - 55
The 10th term is - 55

Answer 11

wait....I must of messed up on the 3rd one...
find the 10th term of sequence 2,5,8
d = 3
a1 = 2
n = 10
an = a1 + (n - 1)3
a10 = 2 + (10 - 1)3
a10 = 2 + 27
a10 = 29
The tenth term is 29

sorry about that
