React Native Animated setValue() problem?

Actually I'm trying to set value of the animation with setValue() after Animated.timing() is finished and want to use this updated animated value then in a loop animation.

//Initialising animation value=50
const leftAnim = useRef(new Animated.Value(50)).current 
useEffect(() => {
    Animated.timing(leftAnim,{
        toValue:360,
        duration:3000,
        easing:Easing.linear,
        useNativeDriver:false,
    }).start(({finished}) => {
        //Updating animation value=100
        leftAnim.setValue(100)
        //Animated API is not considering the setValue and starting the loop animation with the first value i.e 50 instead of 100
        Animated.loop(
            Animated.timing(leftAnim,{
                toValue:360,
                duration:5000,
                easing:Easing.linear,
                useNativeDriver:false
            })
        ).start()
    })
},[])

Am I doing something wrong? Is there a better way to do it?
