Answer» The 10th term of A.P is 19√2.Explanation:To FIND : 10th term of and AP.We have A.P• √2, 3√2, 5√2, 7√2...So,First term is √2Second term is 3√2.Common difference = SECOND term - First term Common difference = 3√2 - √2 Common difference = 2√2Common difference is 2√2.We KNOW,General form of A.P is a, a+d, a+2d, a+3d ...[Where, a is first term and d is common difference]And, if we want to find nth term of AP than formula is , [N is nth terms]Now, Put a and d in formula : = √2 + (10 - 1) × 2√2 = √2 + (9) × 2√2 = √2 + 18√2 = 19√2Thus,The 10th term of A.P is 19√2. |
