Please helpI need to write 4+6+8+10 in sigma notation
would it be sigma sign in middle (3) on top of sign, n=0 on bottom of signma notation and to the right it would be (4+2n)
so it would look like
(3)
(sigma in middle) (4+2n)
n=0

Yours will work
If I recall, the index in sigma notation usually starts with 1, so you could have
4
∑ (2+2n)
n=1
There is no unique way to state the result.

So this one is confusing me: limit of n as it approaches infinity of (n{SIGMA}i=1) (1/(2^i) *the n is on top of the sigma notation and i=1 is at the bottom. I understand that 'i' would equal (n(n+1))/2 however the algebra from there …
