Q. Find the numerical answer to the summation given below.\newlinen=092(6n+3) \sum_{n=0}^{92}(6 n+3) \newlineAnswer:
  1. Recognize arithmetic series: To solve the summation, we need to recognize that it is the sum of an arithmetic series. The general formula for the sum of an arithmetic series is S=n2(a1+an)S = \frac{n}{2}(a_1 + a_n), where nn is the number of terms, a1a_1 is the first term, and ana_n is the last term. First, we need to find the number of terms in the series.
  2. Find number of terms: The series starts at n=0n=0 and ends at n=92n=92, so the number of terms is 920+1=9392 - 0 + 1 = 93 terms.
  3. Find first term: Next, we need to find the first term of the series when n=0n=0. Plugging n=0n=0 into the formula 6n+36n+3 gives us the first term: a1=6(0)+3=3a_1 = 6(0) + 3 = 3.
  4. Find last term: Now, we need to find the last term of the series when n=92n=92. Plugging n=92n=92 into the formula 6n+36n+3 gives us the last term: an=6(92)+3=552+3=555a_n = 6(92) + 3 = 552 + 3 = 555.
  5. Use sum formula: We can now use the sum formula for an arithmetic series: S=n2(a1+an)S = \frac{n}{2}(a_1 + a_n). Plugging in the values we have: S=932(3+555)S = \frac{93}{2}(3 + 555).
  6. Perform calculation: Perform the calculation inside the parentheses first: 3+555=5583 + 555 = 558.
  7. Multiply by number of terms: Now multiply this sum by the number of terms divided by 22: S=(932)×558S = (\frac{93}{2}) \times 558.
  8. Perform final calculation: Perform the multiplication to find the sum: S=46.5×558S = 46.5 \times 558.
  9. Perform final calculation: Perform the multiplication to find the sum: S=46.5×558S = 46.5 \times 558.Finally, calculate the product to get the numerical answer: S=25947S = 25947.
