(a) 7 ∑ j=3 (4 j −1) = (b) 5 ∑ i=3 (i 2 −i) = Answer(s) submitted: • • (incorrect) Problem 2. (0 points) Write out the following sums, one term for each value of k. Simplify each term as much as possible, but do not enter decimals. For example, enter 1+4+9 instead of 12 +2 2 +3 2 or 14, or enter 1/2+1/2 instead of 0.5+0.5 or 1. The purpose of this problem is for you to show that you know how to interpret summation notation and write all of the terms in a sum, which is why you are being told not to reduce your answers very much. (1) 5 ∑ k=0 2 k = (2) 5 ∑ k=2 1 k = (3) 8 ∑ k=1 k 2 = (4) 8 ∑ k=1 1 8 = (5) 6 ∑ k=1 4k = Answer(s) submitted: • • • • • (incorrect) Problem 3. (0 points) Write the sum 1+2+3+4+5+6+7 using sigma notation. The form of your answer will depend on your choice of the lower limit of summation. ∑k= Answer(s) submitted: • (incorrect) Problem 4. (0 points) Write the sum −3+5−7+9−11+13−15+17−19 using sigma notation. The form of your answer will depend on your choice of the lower limit of summation. ∑k= Answer(s) submitted: • (incorrect) Problem 5. (0 points) Write the sum using sigma notation: 2+4+6+8+···+60 = ∑ A n=1 B. Then A = B = Answer(s) submitted: • • (incorrect) Generated by c WeBWorK, http://webwork.maa.org, Mathematical Association of America 1
