Q. Find the numerical answer to the summation given below.\newlinen=097(6n+7) \sum_{n=0}^{97}(6 n+7) \newlineAnswer:
  1. Identify Common Difference and Terms: We need to find the sum of the arithmetic series given by the formula n=097(6n+7)\sum_{n=0}^{97}(6n+7). To do this, we will first identify the common difference and the number of terms in the series.\newlineThe common difference is 66, and since we are starting from n=0n=0 and going up to n=97n=97, there are 9898 terms in total.
  2. Split Summation into Two Parts: We can split the summation into two separate summations: one for the 6n6n term and one for the constant 77. This gives us n=0976n+n=0977\sum_{n=0}^{97}6n + \sum_{n=0}^{97}7.
  3. Calculate Sum of 66n Terms: Let's first calculate the sum of the 6n6n terms. The sum of an arithmetic series can be found using the formula S=n2(first term+last term)S = \frac{n}{2}(\text{first term} + \text{last term}). The first term when n=0n=0 is 6×0=06\times 0 = 0 and the last term when n=97n=97 is 6×97=5826\times 97 = 582. So we have S=982(0+582)S = \frac{98}{2}(0 + 582).
  4. Calculate Sum of Constant 77 Terms: Performing the calculation for the sum of the 6n6n terms, we get S=49×582=28518S = 49 \times 582 = 28518.
  5. Add Two Sums for Total: Now we calculate the sum of the constant 77 terms. Since this is a constant added 9898 times, the sum is simply 98×798 \times 7.
  6. Add Two Sums for Total: Now we calculate the sum of the constant 77 terms. Since this is a constant added 9898 times, the sum is simply 98×798 \times 7.Performing the calculation for the sum of the constant 77 terms, we get 98×7=68698 \times 7 = 686.
  7. Add Two Sums for Total: Now we calculate the sum of the constant 77 terms. Since this is a constant added 9898 times, the sum is simply 98×798 \times 7.Performing the calculation for the sum of the constant 77 terms, we get 98×7=68698 \times 7 = 686.Finally, we add the two sums together to get the total sum of the series: 28518+68628518 + 686.
  8. Add Two Sums for Total: Now we calculate the sum of the constant 77 terms. Since this is a constant added 9898 times, the sum is simply 98×798 \times 7.Performing the calculation for the sum of the constant 77 terms, we get 98×7=68698 \times 7 = 686.Finally, we add the two sums together to get the total sum of the series: 28518+68628518 + 686.Adding the two sums, we get 28518+686=2920428518 + 686 = 29204. This is the sum of the series from n=0n=0 to n=97n=97 of the expression (6n+7)(6n+7).
