An arithmetic sequence.
Subtract the previous one from the current one.

1 2 3 4 5 6 7 8 9 10 11 12 The common difference between consecutive terms is 1.
A common difference is a mathematical concept that appears in arithmetic sequences. An arithmetic sequence is a sequence of numbers, U(1), U(2), ... generated by the following rule: U(1) = a U(2) = U(1) + d U(3) = U(2) + d and, in general, U(n) = U(n-1) + d that is, you have a starting number a and, after that, each term in the sequence is found by adding a fixed number, d, to the previous term in the sequence. An equivalent formulation is U(n) = a + (n-1)*d The difference between any two consecutive terms is d and this is the common difference. For example, in the sequence 3, 7, 11, 15, 19, .... the common difference is 4. This is because 7-3 = 4 11-7 = 4 15-11 = 4 and so on.
Adding together the terms and dividing them by the number of terms gives the arithmetic mean.
Subtract the previous one from the current one.
One possibility is that the sequence continues: 46, 94, 190, ... The difference between the given terms is 3, 6, 12; so the sequence continues by doubling the previous difference: 24, 48, 96, ... and adding it to the previous number.

Adding like terms can be like adding fractions. You can only add fractions with a common denomonator. You can only combine terms together if they are like. Think of like terms as denomonators. You can only add if they are like.

There is no difference in the common usage of these terms.
If the terms get bigger as you go along, the common difference is positive. If they get smaller, the common difference is negative and if they stay the same then the common difference is 0.

It is: 2x and 5x are like terms Addition: 2x+5x = 7x Multiplication: 2x*5x = 10x2

A geometric sequence (aka Geometric Progression or GP) is one where each term is the previous term multiplied by a constant (the common difference) As division is the inverse of multiplication, each term can also be said to be the previous term divided by the reciprocal of the constant. The sum Sn of n terms of a GP can be found by: Sn = a(1 - rⁿ)/(1 - r) = a(rⁿ - 1)/(r - 1) where: a is the first term r is the common difference n is the number of terms If the value of the common difference is between -1 and 1 (ie |r| < 1), then the sum of the GP will be finite since as n→ ∞ so rⁿ → 0, and will be: S = a/(1 - r)
