Notifications Mark All Read. A series of number is termed to be in arithmetic progression when the difference between two consecutive numbers remain the same. It also means that the next number can be obtained by adding or subtracting the constant number to the previous in the sequence. Therefore, this constant number is known as the common difference d. For example, 3, 6, 9, 12 is an AP as the difference between two consecutive terms is three which is fixed. If the ratio of any two successive terms is invariably similar, then the sequence is termed a geometric progression.

Arithmetic progression AP or arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a constant, d to the preceding term. The constant d is called common difference. If each term of an AP is increased, decreased, multiplied or divided by the same non-zero constant, the resulting sequence also will be in AP.

Important Formulas - Sequence and Series Arithmetic Progression AP Arithmetic progression AP or arithmetic sequence is a sequence of numbers in which each term after the first is obtained by adding a constant, d to the preceding term.

In an AP, sum of terms equidistant from beginning and end will be constant. Please see 1. Opara Hi great one, thanks a million for the enlightenment. Under the section "5. It is HP only. Mohinish You can establish a relationship between the first few terms.

For instance consider the following incomplete sequence. You can see that each term is twice it's predecessor. Unknown number is I hate sequence and series but after watching these formulas arrange in such an efficient manner i now i feel relaxed now i am not soooooooo much confuse so thanks.

## Important Formulas - Sequence and Series

Progressions or Sequences and Series are numbers arranged in a particular order such that they form a predictable order. By predictable order, we mean that given some numbers, we can find next numbers in the series. A sequence of numbers is called an arithmetic progression if the difference between any two consecutive terms is always same. In simple terms, it means that next number in the series is calculated by adding a fixed number to the previous number in the series. This fixed number is called the common difference. A sequence of numbers is called a geometric progression if the ratio of any two consecutive terms is always same.
