FAQs on NCERT Solutions for Class 10 Maths Chapter 5 - Exercise
1. What are Some of the Important Concepts of the Chapter Arithmetic Progression?
Ans: Arithmetic progression is a sequence of numbers where the difference between two consecutive numbers is the same. This difference between two consecutive terms is called the common difference. As long as the sequence or series of numbers follow this rule they are said to be in an AP.
An AP can be commonly written as:
a, a + d, a + 2d, a + 3d, a + 4d, ......, a + (n - 1)d.
If the first term a and the common difference d of an AP is known we can find the value of the nth or any term of an APย easily.
an = a + (n - 1)d
The sum of the AP can be calculated using the formula:
S = n/2(2a + (n - 1)d)
2. How can the Sum of an AP be Calculated? Derive the Formula Mathematically for the Same.
Ans: The sum of an AP is the sum of each term of the AP. The summation of each term of an AP can be tiresome in longer progressions. Also, the APs with a negative common difference, finding the sum of AP can be tricky. The sum of the AP can be calculated using the following formula:
S = n/2(2a + (n - 1)d)
Derivation:ย
Sn = a1 + (a1 + d) + (a1 + 2d) + .... (a1 + (n - 1)d). (i)
Sn = an + (an - d) + (an - 2d) + ...(an - (n - 1)d). (ii)
Adding both the equations and solving,
2Sn = n(a1 + an)
an = a1 + (n - 1)d
2Sn = n(a1 + a1 + (n - 1)d)
2Sn = n(2a1 + (n - 1)d)
S = n/2(2a1 + (n - 1)d)
The formula for sum of AP can be written as:
S = n/2(2a + (n - 1)d)
