Please note that I am talking about a series and NOT a sequence

Let (an) and (bn) be sequences of real numbers with an ≥ 0 for all n ∈ N. Suppose that an ≤ bn for all n ∈ N and that the sum of all bk from k=1 to infinity is convergent. Prove...

I couldn't figure out how to do this :/

an=e(-1/sqrt(n)) Apparently in converges and the limit is 1 but I'm not really sure how to do this type of problem with a limit of ex {n2e-n} Limit converges to 0? How?...

A series is given as below, 2-2^2/(x+1)+2^3/(x+1)^2 -2^4/(x+1)^3 +⋯+2^r/〖(-(x+1)〗^(r-1) +⋯ I) Find the set of values of x such that the series converges...

FORMULAE FOR SERIES +N/2+N/4+N/8......1

Can anyone explain how you prove a general term is true for a series, un+1=un/1+un u1=2 (i) find u2 and u3 (ii) Hence suggest an expression for un and so I have found...

A. summation of negative forty five times n from n equals zero to fifteen B. summation of the quantity negative nine plus five n from n equals zero to fifteen C. summation of the quantity...

abbcccddddeeeee........... what will be the 126th digit?

Determine whether the sequence is increasing, decreasing, or not monotonic. an = 1/(6n+7) Is the sequence bounded? Yes or No? Explain.

Determine whether the sequence is increasing, decreasing, or not monotonic. an = 4n(−7)n Is the sequence bounded? Yes or No? Explain.

I have a series (Un)n∈Ν. U0=2 and Un+1=1/4(Un)+1. I need to find a series (Vn)n∈Ν and a∈R such that Vn=Un+a and that (Vn) is geometric.

A ball is thrown vertically upwards from the ground. It rises to a height of 10m and then falls and bounces. After each bounce it rises vertically to 2/3 the height from which it fell. (i)...

The first 3 terms of a geometric expression are x, 10 − x ,and 2x + 1 where x > 0. Find the value of the common ratio, r.

Sum to n terms of series 1^2 - 2^2 + 3^2 - 4^2 + 5^2 - 6^2 +.......

I don't understand how to find the sum if I don't know what term the last one (252)? How would I determine which term this is (t of ?=252)

Hello, could you help me find the formula for this series, please? How do I go about it? 4,9,16,25,...I know it starts with adding 5 and adding 2 more with every number, so adding 7 next,...
