Question

Use the finite sequence. Write the related series. Then evaluate the series. 26, 29, 32, 35, 38, 41, 44

Answer 1

you will have to try to see a pattern to develop the rule for the summation expression

Answer 2

or if you dont need to use summation notation .... just place a + between all the numbers instead of a ,

Answer 3

26+3n, where n is the number in the sequence
so the 1st will be 29
2nd will have n =2 and thus 32

Answer 4

thats a fine rule

Answer 5

thats what i got so far

Answer 6

then sum that form n=0 to n=?

Answer 7

till where?

Answer 8

well, if counting very few terms is beyond your abilities ... you can always revert to the rule you devised ....

26 + 3n = 26; when n=0

26 + 3n = 44; when n=?

Answer 9

26+3(6)=44

Answer 10

then n = 0 to 6 :)

Answer 11

Use the finite sequence. Write the related series. Then evaluate the series. 26, 29, 32, 35, 38, 41, 44
A. 26 + 29 + 32 + 35 + 38 + 41 + 44 = 219
B. 26 + 29 + 32 + 35 + 38 + 41 + 44 = 245
C. 26 - 29 - 32 - 35 - 38 - 41 - 44 = -193
D. 26 + 29 + 32 + 35 + 38 + 41 + 44 = 201

Answer 12

\[\sum_{n=0}^{6}~26+3n\]

Answer 13

i see, then the summation notation is beyond the scope

Answer 14

i got B

Answer 15

is it correct?

Answer 16

26+3(0)
26+3(1)
26+3(2)
26+3(3)
26+3(4)
26+3(5)
26+3(6)
-------
6(26) + 3(0+1+2+...+6)

156 + 3(21)

Answer 17

B was correct :).

Answer 18

it was :)

Answer 19

OMG i got a medal :)

Answer 20

26(7) was what i typoed on
