Statement 1 If a, b, c are in AP, (b+c-a),(c+a-b),(a+b-c) are in AP and Statement 2 If a1, a2 a3

step 1 Hi, the first we look at a statement two here. Statement two says that, portion number 174, if A

Statement 1 If a, b, c are in AP, (b+c-a),(c+a-b),(a+b-c)...

Statement 1
If $\mathrm{a}, \mathrm{b}, \mathrm{c}$ are in AP, $(b+c-a),(c+a-b),(a+b-c)$ are in AP
and
Statement 2 If $\mathrm{a}_{1}, \mathrm{a}_{2} \mathrm{a}_{3}$ are in $\mathrm{AP}$,
$a_{1}+k, a_{2}+k, a_{3}+k$ where $k \neq 0$ are also in AP

Key Concepts

Arithmetic Progression

An arithmetic progression (AP) is a sequence of numbers in which the difference between any two successive members is a constant, known as the common difference. This concept is fundamental in algebra and number theory because it provides a structured way to analyze sequences and series and to formulate and prove properties about them.

Translation Invariance in AP

Translation invariance in the context of arithmetic progressions means that if a constant is added to every term of an AP, the resulting sequence remains an arithmetic progression with the same common difference. This property underlies the idea that the relative spacing between terms is what defines the progression, not their absolute values.

Linear Transformations of AP Terms

Linear transformations, such as taking linear combinations or symmetrically modifying the terms of an arithmetic progression, often preserve the structure of an AP. When expressions are formed by adding and subtracting terms—like in creating new terms from existing ones in a balanced way—the common difference tends to be maintained, ensuring that the transformed sequence is also an arithmetic progression.
