Question

4. Express the series below in summation notation for the specified number of terms.
b. 10 + 14 + 18 + 22

Answer 1

each next term is +4
series starts from "10"
there are 4 terms in the series

Answer 2

so how would we put that into the equation

Answer 3

\[\huge\color{blue}{ \sum_{n=10}^{4} ~~4(\color{red} { n } -1)+10 } \]

Answer 4

red n is nth term, like 2nd term 2rd term....

Answer 5

whata bout 1/2+2/3+3/4+4/5+5/6

Answer 6

so for 1st term you would put in 1

1st term = 4(1-1) + 10 = 0 + 10 = 10
2nd term = 4(2-1) + 10 = 4 + 10 = 14
3rd term = 4(3-1) + 10 = 8 + 10 = 18
4th term = 4(4-1) + 10 = 12 + 10 = 22


I don't get the last you thing you wrote

Answer 7

4. Express the series below in summation notation for the specified number of terms.
\[\frac{ 1 }{ 2 }+\frac{ 2 }{ 3}+\frac{ 3 }{ 4 }+\frac{ 4 }{ 5 }+\frac{ 5 }{ 6 }\]

Answer 8

\[\huge\color{green}{ \sum_{n=1}^{5} ~~\frac{n}{n+1} }\]

Answer 9

How does this one look :) ?

Answer 10

good

Answer 11

whata bout this

Answer 12

Express the series below in summation notation for the specified number of terms.
9. 0 + 3 + 8 + 15 + 24 + 35 + 48 + 63 + 80

Answer 13

+3, +5, +7, +9, +11 ....

\[\huge\color{blue}{ \sum_{n=2}^{9} ~~(2n+1) }\]
