Do calculation in every two cell in merge and merge manner /

[Happydayyy (22035153d)]

In the output file of column H, the average F is come from the two number of average of column G. For example, H2 is from G2/G3, H4 is come from G4/G5. How can I do the merge and merge of every two cell of column G and then I need to do the set the formula of “G2/G3” and get the 5 d.p.
Thank you so much!

I am writing the robot in this way, but it can’t fulfill my target.

Can anyone help me to edit?
Many thanks
