Q. Find the numerical answer to the summation given below.n=0∑97(6n+7)Answer:
Identify Common Difference and Terms: We need to find the sum of the arithmetic series given by the formula ∑n=097(6n+7). To do this, we will first identify the common difference and the number of terms in the series.The common difference is 6, and since we are starting from n=0 and going up to n=97, there are 98 terms in total.
Split Summation into Two Parts: We can split the summation into two separate summations: one for the 6n term and one for the constant 7. This gives us ∑n=0976n+∑n=0977.
Calculate Sum of 6n Terms: Let's first calculate the sum of the 6n terms. The sum of an arithmetic series can be found using the formula S=2n(first term+last term). The first term when n=0 is 6×0=0 and the last term when n=97 is 6×97=582. So we have S=298(0+582).
Calculate Sum of Constant 7 Terms: Performing the calculation for the sum of the 6n terms, we get S=49×582=28518.
Add Two Sums for Total: Now we calculate the sum of the constant 7 terms. Since this is a constant added 98 times, the sum is simply 98×7.
Add Two Sums for Total: Now we calculate the sum of the constant 7 terms. Since this is a constant added 98 times, the sum is simply 98×7.Performing the calculation for the sum of the constant 7 terms, we get 98×7=686.
Add Two Sums for Total: Now we calculate the sum of the constant 7 terms. Since this is a constant added 98 times, the sum is simply 98×7.Performing the calculation for the sum of the constant 7 terms, we get 98×7=686.Finally, we add the two sums together to get the total sum of the series: 28518+686.
Add Two Sums for Total: Now we calculate the sum of the constant 7 terms. Since this is a constant added 98 times, the sum is simply 98×7.Performing the calculation for the sum of the constant 7 terms, we get 98×7=686.Finally, we add the two sums together to get the total sum of the series: 28518+686.Adding the two sums, we get 28518+686=29204. This is the sum of the series from n=0 to n=97 of the expression (6n+7).
