Here a1 = -6, a2 = -1, a3 = 4 & a4 = 9
d = a2-a1 = -1-(-6) = -1+6 = 5
d = a3-a2 = 4-(-1) = 4+1 = 5
d = a4-a3 = 9-4 = 5
Therefore the common difference d = 5
arithmetic sequence. for example: 4,8,12,16 is an arithmetic sequence because it is 4+4+4+4. hope this helps!

This is the real question what is the 19th term in the arithmetic sequence 11,7,3,-1,...? _________________________________________________________ Looks like you just subtract 4 each time, as : 11,7,3,-1,-5,-9, ......
No it is not.U(2) - U(1) = 6 - 2 = 4U(3) - U(2) = 18 - 6 = 12Since 4 is different from 12, it is not an arithmetic sequence.
As you are taking 3 away each time, the 5th term will be -5.
It is the start of an arithmetic sequence.

The 19th term of the sequence is 16.

None, since there is nothing to link y to the sequence.
To form a linear (or arithmetic) sequence you need two things: a starting value and the common difference. You have provided the common difference but not the starting value. If the starting value was a, then the nth term in the sequence would beT(n) = a + 5/4*(n - 1).
In order to determine whether or not this is an arithmetic sequence, there must be at least 3 numbers.
Sequence that has addition or (subtractions*) subtraction will be +(-4)

There are different answers depending upon whether the sequence is an arithmetic progression, a geometric progression, or some other sequence. For example, the sequence 4/1 - 4/3 + 4/5 - 4/7 adds to pi
No it is not.U(2) - U(1) = 6 - 2 = 4U(3) - U(2) = 18 - 6 = 12Since 4 is different from 12, it is not an arithmetic sequence.
