i want to auto increment on when a new record is created using triggers. i have customer object and customer_serial_No field whenever a customer is created customer_Serial_No is incremented

As suggested try to use Auto number field to auto-increment as this can be taken care of by the system. If you still need to have trigger use the customer_serial_no to increment it each time based on the highest value, make sure to create a custom index for this field as it will lead to SOQL error when the data size increases.
