so i've already answered one of the questions i asked yesterday. thanks for the username damon. yeah it was a typo.

I'm gonna repost a question. Please please... someone help me.

*The first and the second term of a progression are "a" and "b" respectively. what is the third term if the progression is harmonic?

- is it 1/c? that's my guess for the question. but i think our teacher wants a solution how we solved for it..

thank you in advance to whoever will answer.

XOXO
