An infinite series is the sum of terms in an infinitely long sequence, but taking the sum of terms in a finite portion of the sequence is called a partial sum. Explore these two concepts through examples of five types of series: arithmetic, geometric, harmonic, al...
Answer to: 1) Determine the sum of the series. \sum_{n = 1}^{\infty} \left ( \frac{2^n + 9^n}{12^n} \right ) 2) Find the limit of the sequence a_n...

Determine the SUM of the series: Determine the SUM of the series: \sum_{n=1}^{\infty} \frac{(8(9)^{2n})}{(5)^{3n Find the sum of the infinite series. \sum \frac{2}{(n + 1)(n + 3)} Find a formula ...
A convergent series is one in which the sum of all the terms approaches a finite value as the number of terms increases. A divergent series, on the other hand, is one in which the sum of the terms either increases without bound or oscillates between positive and negative values. ...
Use the Integral Test to determine whether the infinite series is convergent. Sum of (n^2)/((n^3 + 4)^(7/2)) from n = 1 to infinity. Use the integral test to determine whether the infinite series \sum_{x = ...

Specifically, we show that targeted knockdown of the GR in the NAc astrocytes enhanced conditioned responses to morphine, with a concomitant inhibition of morphine-induced neuronal excitability and plasticity. Interestingly, GR knockdown did not influence sensitivity to cocaine. Further analyses revealed ...
