Answer:

y = 105 ÷ 6 = 35/2

Step-by-step explanation:

∵ 15/3 = 2y/7

∴ 2y × 3 = 15 × 7

∴ 6y = 105

∴ y = 105 ÷ 6 = 35/2

Does (-2)^n/( 3^n+1) converge or diverge?

hodyreva [135]

$\left|\dfrac{(-2)^n}{3^n+1}\right|=\dfrac{2^n}{3^n+1}$

As $n\to\infty$ , the sequence $a_n=\left(\dfrac23\right)^n$ converges to zero.

If you're talking about the infinite series

$\displaystyle\sum_{n\ge0}\dfrac{(-2)^n}{3^n+1}$

well we've shown by comparison that this series must also converge because we know any geometric series $\sum\limits_n r^n$ will converge as long as $|r|$ .
