Sample Test Paper  for Class 10 - Arithmetic Progression


Arithmetic Progression Definition.

 Arithmetic progression (AP) is a sequence of numbers in which each term after the first is found by adding a constant, called the common difference, to the previous term. For example, the sequence 3,6,9,12... is an arithmetic progression with a common difference of 3. The nth term of an arithmetic progression can be found using the formula: a + (n-1)d, where a is the first term and d is the common difference. The sum of an arithmetic progression can be found using the formula: (n/2)(2a + (n-1)d), where n is the number of terms in the progression.

Arithmetic progression 

An arithmetic progression (AP) is a sequence of numbers in which each term after the first is found by adding a constant, called the common difference, to the previous term. For example, the sequence 2, 5, 8, 11, 14, ... is an arithmetic progression with a common difference of 3. The nth term of an arithmetic progression can be found using the formula: a + (n-1)d, where a is the first term and d is the common difference. The sum of an arithmetic progression can be found using the formula: (n/2)(2a + (n-1)d), where n is the number of terms in the progression.
