General Term
We come across various patterns in our daily life. Arithmetic Progression in short AP is a sequence of numbers or terms in which each term except the first term is obtained by adding a fixed number or constant to the preceding term. This constant or fixed number is called common difference denoted by d.
The general term or nth term of AP is given by tn = a + (n – 1)d, where a is the first term, d is the common difference and n is the number of term.
Common difference is given by d = t2 – t1 = t3 – t2 = ……..
The nth term is also denoted with l or b.
General term of AP is tn = a + (n – 1)d
