Write the series in sigma notation.
1/4+1/2+3/4+1+5/4+3/2

  • Algebra -

    rewrite as
    1/4 + 2/4 + 3/4 + 5/4 + 6/4

    so the general form of the terms are n/4

    ∑ n/4 , where n=1 to 4

    write the "n=1" below the ∑ sign, and 4 above it

    Hello Reiny,

    Thanks for the help however it's a multiple choice and ther is non like that.

    I have:

    A. 1/4 to the left of the e symbol. 5 on top n=1 on the bottom and n to the right.

    b. 1/4 to the left, 6 on top, n to the right and n=1 on the bottom.

    c. 5 on the top, n=1 on the bottom and to the right n/n+3

    d. 6 on the top. n=1 on the bottom and to the right n/n+3.

    I obviously can't count to 5, only saw 4 terms, ha ha

    you should have seen that

    how about

    ∑ n/4 , where n=1 to 5
    = (1/4) ∑ n , where n=1 to 5

    Please check: 1.Write in expanded form: this is a sigma notation- 4 on top signma in middle k=1 on bottom to right of sigma is (k-1)(k-2) I solved: k=1 (1-1)(1-2)=0(-1)=0 K=2 (2-1)(2-2) = 1(0)=0 k=3(3-1)(3-2)=2(1)=2 k=4 (4-1)(4-)=3(2)=6 …
