Write the following in summation notation:5+8+11+......+71+74

Answer 1

Summation of i + 3, ( i = 5 -> 74)

Answer 2

\[\sum_{3}^{72}i+3\]

Answer 3

i am sorry; the bottom number should be 2

Answer 4

2+3=5 and 71 (not 72) + 3= 74

Answer 5

my basic math is terrible!

Answer 6

why do you use i instead of n? Just asking because usually i is reserved for complex notation.

Answer 8

this is wrong I think...

Answer 9

I used i because that is what the problem had in it; sometimes it is just a variable

Answer 10

\[\sum_{i=0}^{23}5+3i\]is the answer

Thanks! much better

Answer 12

I like to use i for "index", its personal preference.

Answer 13

\[\sum_{n=2}^{25}3n-1\]
