You have not mentioned the size for in parameter varchar,
Try below code.
DELIMITER $$
CREATE DEFINER = CURRENT_USER PROCEDURE getReceiptNumber(IN bankcode VARCHAR(10),IN receipttype VARCHAR(10),OUT seq INT)
BEGIN
UPDATE receipt_number
SET seq_number = (seq_number + 1)
WHERE bank_code = bankcode AND receipt_type = receipttype;
SELECT seq_number FROM receipt_number WHERE bank_code = bankcode AND
receipt_type = receipttype INTO seq;
END$$
DELIMITER ;
