Q. Find the numerical answer to the summation given below.n=0∑92(6n+3)Answer:
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=2n(a1+an), where n is the number of terms, a1 is the first term, and an is the last term. First, we need to find the number of terms in the series.
Find number of terms: The series starts at n=0 and ends at n=92, so the number of terms is 92−0+1=93 terms.
Find first term: Next, we need to find the first term of the series when n=0. Plugging n=0 into the formula 6n+3 gives us the first term: a1=6(0)+3=3.
Find last term: Now, we need to find the last term of the series when n=92. Plugging n=92 into the formula 6n+3 gives us the last term: an=6(92)+3=552+3=555.
Use sum formula: We can now use the sum formula for an arithmetic series: S=2n(a1+an). Plugging in the values we have: S=293(3+555).
Perform calculation: Perform the calculation inside the parentheses first: 3+555=558.
Multiply by number of terms: Now multiply this sum by the number of terms divided by 2: S=(293)×558.
Perform final calculation: Perform the multiplication to find the sum: S=46.5×558.
Perform final calculation: Perform the multiplication to find the sum: S=46.5×558.Finally, calculate the product to get the numerical answer: S=25947.
