Giải thích các bước giải:

Đặt A= 1/4+1/16+1/36+1/64+1/100+1/144+1/196

= 1/2^2+ 1/4^2+ 1/6^2+….+ 1/16^2

= 1/2^2.( 1+ 1/2^2+ 1/3^2+…+ 1/8^2)

Ta có 1+ 1/2^2+ 1/3^2+…+ 1/8^2< 1+ 1/1.2+ 1/2.3+….7.8= 1+ 1-1/2+ 1/2- 1/3+….+ 1/7- 1/8

= 2- 1/8< 2

Nên ( 1+ 1/2^2+ 1/3^2+…+ 1/8^2)< 2

=> A< 1/2^2 nhân 2= 1/2

Vậy A< 1/2
