Math Problem Statement
1001 ∑ (3k-1) K=1 Use wolfram Alpha on question 1-4 now solve this
Solution
The summation you've provided is:
Let's break down how to solve it.
-
Separate the Sum: You can separate this sum into two parts:
-
Factor Out Constants:
- For the first part:
- For the second part: , since summing 1 over 1001 terms simply gives 1001.
-
Evaluate the Sum of : Using the formula for the sum of the first integers, , we find:
-
Substitute Back: Now, calculate each term:
-
Combine the Results:
Final Answer:
Would you like further explanation on any step, or assistance with questions 2-4?
Here are five related questions to expand on this topic:
- How does the formula for summing an arithmetic sequence differ from this summation approach?
- What happens if we change the upper limit from 1001 to a different number?
- How would the answer differ if we had a different constant multiplier in ?
- Can we apply similar steps if was instead ?
- How would the approach change if the terms alternated signs, such as for even and for odd ?
Tip: For large summations, breaking the expression down and factoring constants often simplifies the calculation.
