Application +4 | -1

n

arithmetic means are inserted between two sets of numbers

a, a^2 \& b, b^2

where

a, b \in R

. Suppose

m

th mean between these two sets of numbers is same, then

a

+b

equals

View answer and explanation

Correct option: D

\frac{m-n-1}{m}

Option D (

\frac{m-n-1}{m}

) is correct because by equating the m-th arithmetic means of the two sets, we can derive the relationship a+b = (m-n-1)/m.
