Since its simple pendulum we have Potential energy and Kinetic energy.
The extreme left position is B.
The extreme right position is C.
The center or mean position is A.
When pendulum is in mean position then there is no Potential energy only maximum kinetic energy hence the formula at A will be:
A=K. E=K=1/2*m*v^2 and P.E=U=0
When pendulum swings to the extreme left then the kinetic energy will convert to the potential energy. At position B the potential energy will be maximum.
B=P. E=U= m*g*h and K.E=K=0
And then the pendulum returns to position A and then to position C where again Potential energy is maximum and all the Kinetic energy converts to potential energy.
C=U=P. E=m*g*h and K. E=K=0

The extreme right position is C.
