How will we find equivalent cell if in series cells are connected like a negative electrode with negative electrode of other cell  find its equivalent and also tell me formula

When cells are connected in series, the equivalent emf will add up if the negative of one cell is connected to the positive of other cell.
 
E = E1 + E2
 
However, in your case, the negative of one cell is connected to negative of other cell. So, the two emf's will try to oppose each other. So, we will get
 
E = E1 - E2
