Question

what is the common difference between for an AP root 5,root 20,root 45​

Answer 1

Answer:

i think tere is a common difference of root 5

root 5 = root 5 (a1)

root 20= 2root 5(a2)

and,

root 45= 3root 5(a3)

Now,

common difference: a2-a1 = a3-a2

2root 5-root 5 = 3root 5-2root 5

root 5 = root 5

therefore LHS = RHS
