And you MUST solve the following summation problems (You have to apply formulas to solve the following summation problems. Writing the summations in expanded forms won't be considered as correct answers. Some examples of correct answers are provided here - Help on HW3​, Part2.pdf ↓⊵. Finally, you don't have to provide a final numerical value, an intermediate form will be sufficient. For example, the three answers in the attached example answers are complete because the summation formulas have been applied, but they are left in intermediate form because they have not been evaluated into a single numerical value.) - 1. i=12∑500​(2i−25​) 2. j=0∑20​(4j2−(−3)j) ∗∗ Please note that i=0∑n​i2=02+12+22+…+(n−1)2+n2=0+i=1∑n​i2=i=1∑n​i2 3. j=38∑70​(2j+3⋅4j) P.S: You must make use of the formulas provided in summation formula updated.pdf ₫ Minimize File Preview to solve the problems.
