Question

Express the series using sigma notation. 5 + 8 + 11 + 14 + 17...

Answer 1

Answer: 73ow

Step-by-step explanation: yes s

Answer 2

so we see that each term is 3 more than the previous
so
we start with an=a1+d(n-1)
an=nth term
a1=first term
d=common difference
n=which term

first term is 5 and common differnce is 3
an=5+3(n-1)
an=5+3n-3
an=2+3n

so

ok, sigma notation

`\sum\limits^b_(n=a) {f(n)}`
n=index of summation
a=first value of n
b=last value of n
and f(n) is the formula for the terms
so

the formula is 2+3n
the first value is 1
the last is ∞
so

`\sum\limits^\infty_(n=1) {3n+2}` represents the series
