Sir,my age is 18 and my height is 5f 2cm iam observing my height from 15 but there is slow growth why this happens there is any possible for 5f.7cms?

Sorry, doubtful: Based on your age and the trajectory of your growth it is very unlikely. Genetics and nutrition play a strong role.

It's possible: Your height is determined by your genetics and by your environment. Nutrition is most significant contributor in your environment which contributes to your height. It's also important to get adequate rest and exercise. It you lead a healthy lifestyle it's possible you will grow taller. However, I am certain you look fine now at 5.2!
