Question

Help please!

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

Answer 1

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

Answer 2

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.

Answer 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
