If `A_1,A_2,A_3, A_2 and A_5` are the five A.M.\'s between 2 nd 8, then find the vaslue of `A_1+A_2+A_3+A_4+A_5.

Text Solution

Verified by Experts

Sum of n A.M.s between two numbers is n times the A.M. between them .
` therefore ` Required sum = ` A_(1) , A_(2) , A_(3) , A_(4) , A_(5) = 5 xx ((2+ 8)/(2)) = 25 ` .
