2. Relationship Among the Averages
• A.M > G.M. > H.M.
• E.g. 2,4,8 find AM,GM,HM
• AM =
2+4+8
3
=
14
3
= 4.67
• GM =

2𝑥 4 𝑥 8 =

64 = 4
• HM =

= 3.43

3. Relationship Among the Averages
• A.M = G.M. = H.M.
• E.g. 4,4,4 find AM,GM,HM
• AM =
4+4+4

• GM =

4. Relationship Among the Averages
• A.M > G.M. > H.M.
• A.M = G.M. = H.M.
• A.M ≥ G.M. ≥H.M.
