Q. Find the numerical answer to the summation given below.\newlinen=098(7n+6) \sum_{n=0}^{98}(7 n+6) \newlineAnswer:
  1. Recognize Linear Expression Split: Recognize that the summation is of a linear expression in terms of nn. The summation can be split into two separate summations: one for the 7n7n term and one for the constant term 66.
  2. Apply Summation Rule Linear Term: Apply the summation rule for the first term, which is a linear term 7n7n. The sum of an arithmetic series is given by the formula n=0k(an)=a(k(k+1)2)\sum_{n=0}^{k}(an) = a \cdot \left(\frac{k \cdot (k + 1)}{2}\right), where aa is the constant multiplier of nn. In this case, a=7a = 7 and k=98k = 98.
  3. Calculate Sum First Term: Calculate the sum of the first term using the formula from Step 22.\newlinen=098(7n)=7×(98×(98+1))/2\sum_{n=0}^{98}(7n) = 7 \times (98 \times (98 + 1)) / 2\newline=7×(98×99)/2= 7 \times (98 \times 99) / 2\newline=7×(9702)/2= 7 \times (9702) / 2\newline=7×4851= 7 \times 4851\newline=33957= 33957
  4. Apply Summation Rule Constant Term: Apply the summation rule for the second term, which is a constant term 66. The sum of a constant series is given by the formula n=0k(c)=c(k+1)\sum_{n=0}^{k}(c) = c \cdot (k + 1), where cc is the constant term. In this case, c=6c = 6 and k=98k = 98.
  5. Calculate Sum Second Term: Calculate the sum of the second term using the formula from Step 44.\newlinen=098(6)=6×(98+1)\sum_{n=0}^{98}(6) = 6 \times (98 + 1)\newline=6×99= 6 \times 99\newline=594= 594
  6. Add Final Results: Add the results from Step 33 and Step 55 to get the final answer.\newlineFinal Sum = 33957+59433957 + 594\newline= 3455134551
