Express the series 11 + 18 + 27 +...+ 171 using sigma notation. Usually you would take 2718 and that's the step between numbers, right? (I think its the kvalue?) But 2718=9 and 1811=7. Are we stepping by k+2 here? Like k, k+2

How do I solve this? There are 171 seventh graders eating lunch. This number represents 45% of all of the seventh grades. How many 7th graders are there in the school? Would I take 171 x 45% and add them together or take 171 X .55

how would I....
how would I express the repeating decimal representaion of 1/9 as an infinite series using sigma notaion? Limit of (as n> infinity) (Sigma) 0.1 + (0.1)^2 + (0.1)^3 +... (0.1)^n = 0.11111.... = 1/9 I think drwis did this right, It

Express the sum using summation notation: 1  1/2 + 1/3  1/4 + 1/5  ... (to 3n terms) If I'm doing this right so far, with k=1 (the number on bottom of the sigma), the equation after the sigma would be ((1)^(k+1)) / k I'd be
