.
It means that they talk about the sum of this geometric progression

a*r + a*r ^3 + a*r^5 + a*r^7 + . . . 

which is taken over all odd powers of "r", and this sum does converge to 3.

Dear "students" !

Today is a special day.
Today I solved  16  problems for you and got back  0  (zero,  ZERO)  "thanks"  from you.

It is the absolute record !
    It is just out of limits of my understanding  !
        I never saw it before  !

Thank you very much and wish you to think:   WHO ARE YOU . . .
