-8
A sequence with starting number say a and difference b will be a,a+b,a+2b,a+3b...
So the sequence beginning with -10 and difference -2 is
-10, -10+(-2), -10+(-2x2), ....
-10,-12,-14,-16,-18,-20,-22,-24,-26,-28
The phrase "first difference" is usually associated with a sequence of numbers: a(1), a(2), a(3), a(4), ... . The sequence may have a simple rule for generating the numbers , a complicated rule or, if it is a random sequence, no rule at all.The sequence of first differences is a(2)-a(1), a(3)-a(2), a(4)-a(3), ...
You take the difference between the second and first numbers.Then take the difference between the third and second numbers. If that difference is not the same then it is not an arithmetic sequence, otherwise it could be.Take the difference between the fourth and third second numbers. If that difference is not the same then it is not an arithmetic sequence, otherwise it could be.Keep checking until you think the differences are all the same.That being the case it is an arithmetic sequence.If you have a position to value rule that is linear then it is an arithmetic sequence.

It is the counter that tells you the position of the numbers in the sequence: the first, second and so on.
In a sequence of numbers, a(1), a(2), a(3), ... , a(n), a(n+1), ... he first differences are a(2) - a(1), a(3) - a(2), ... , a(n+1) - a(n) , ... Alternatively, d the sequence of first differences is given by d(n) = a(n+1) - a(n), n = 1, 2, 3, ...
It is an ordered set of numbers in which the difference between any member of the sequence (except the first) and its predecessor is a constant.

An arithmetic sequence is a group or sequence of numbers where, except for the first number, each of the subsequent number is determined by the same rule or set of rules. * * * * * The above answer is incorrect. The rule can only be additive: it cannot be multiplicative or anything else.
The common difference is 6; each number after the first equals the previous number minus 6.
It depends on (a) the first five numbers of what and(b) what sort of sequence.ANY 5 numbers can be put into a quartic sequence. So the answer is: every time.

It is a set of numbers derived from a sequence. The first number in the series is the first number of the sequence. The second number in the series is the sum of the first two numbers of the sequence. The third number in the series is the sum of the first three numbers of the sequence. and so on. Mathematically, a series is easily defined using the sigma notation but that, unfortunately, is beyond the scope of this browser.
It is the counter that tells you the position of the numbers in the sequence: the first, second and so on.
a + 99d where 'a' is the first term of the sequence and 'd' is the common difference.
You subtract any two adjacent numbers in the sequence. For example, in the sequence (1, 4, 7, 10, ...), you can subtract 4 - 1, or 7 - 4, or 10 - 7; in any case you will get 3, which is the common difference.
A geographic sequence is a series of numbers that are ordered in sequence or as part of a special series. A geographic sequence must contain a first and last term.
