Consider a number series: 0.7, 7, 56, 448, 1344, 2688. Let 'P' be the wrong term in this series, and 'Q' be the correct term that should replace 'P'. Based on these values, determine which of the following statements is/are false? Testbook I. (P + Q) is greater than 800 Testbook II. The product of each digit of 'Q' is 63 Testbook III. √P - 87 + Q = 355
