Q. Find the numerical answer to the summation given below.n=0∑95(5n+7)Answer:
Separate Summation Parts: To find the sum of the series, we can separate the summation into two parts: the summation of 5n from n=0 to n=95 and the summation of 7 from n=0 to n=95.
Find Sum of 5n Series: First, let's find the sum of the arithmetic series 5n. The sum of an arithmetic series is given by the formula S=2n(a1+an), where n is the number of terms, a1 is the first term, and an is the last term.
Calculate Sum of 5n: The first term a1 when n=0 is 5(0)=0, and the last term an when n=95 is 5(95)=475. The number of terms is 95−0+1=96.
Calculate Sum of 7: Now we can calculate the sum of the arithmetic series 5n: S=(296)(0+475)=48×475.
Add Two Sums: Calculating the sum gives us S=48×475=22800.
Find Total Sum: Next, we calculate the sum of the constant 7 added 96 times (from n=0 to n=95). This is simply 7 multiplied by the number of terms, which is 96.
Find Total Sum: Next, we calculate the sum of the constant 7 added 96 times (from n=0 to n=95). This is simply 7 multiplied by the number of terms, which is 96.Calculating this sum gives us 7×96=672.
Find Total Sum: Next, we calculate the sum of the constant 7 added 96 times (from n=0 to n=95). This is simply 7 multiplied by the number of terms, which is 96.Calculating this sum gives us 7×96=672.Finally, we add the two sums together to find the total sum of the series: 22800 (sum of 5n) + 672 (sum of 7).
Find Total Sum: Next, we calculate the sum of the constant 7 added 96 times (from n=0 to n=95). This is simply 7 multiplied by the number of terms, which is 96.Calculating this sum gives us 7×96=672.Finally, we add the two sums together to find the total sum of the series: 22800 (sum of 5n) + 672 (sum of 7).Adding these together gives us the final sum: 961.
