Let a, b, c be in AP and k ≠ 0 be a real number. Which of the following are correct? 1. ka, kb, kc are in AP 2. k - a, k - b, k - c are in AP 3. \(\frac{a}{k},\frac{b}{k},\frac{c}{k}\) are in AP Select the correct answer using the code given below:
Let a, b, c be in AP and k ≠ 0 be a real number. Which of the following are correct? 1. ka, kb, kc are in AP 2. k - a, k - b, k - c are in AP 3. \(\frac{a}{k},\frac{b}{k},\frac{c}{k}\) are in AP Select the correct answer using the code given below: Correct Answer 1, 2, and 3
Concept:
If each term of a given AP is multiplied or divided by a non-zero constant k, then the resultant sequence is also an AP with common difference k × d or k / d, where d is the common difference of the given AP.
If a, b and c are in AP then k - a, k - b, k - c are in AP where k ≠ 0.
