Question

if abc are in ap then prove that a + k b + k c+ k​

Answer 1

Answer:

if a,b,c are in the AP then a+k,b+k,c+k are in the AP

Step-by-step explanation:

if a,b,c are in the AP then common difference =b-a

then adding k to the above observations then a+k,b+k,c+k then the common difference =b+k-a-k=b-a

ao a+k,b+k,c+k are in theAP
