162 is the next in the sequence. It's a sequential value. Just multiply the previous number by 3, and you have you answer.

You want to find the time <em>t</em> such that

$\$1000 = \$200 e^{0.04t}$

Divide both sides by $200 :

$\dfrac{\$1000}{\$200} = 5 = e^{0.04t}$

Take the logarithm of both sides:

$\ln(5) = \ln(e^{0.04t}) = 0.04t\ln(e) = 0.04t$

Divide both sides by 0.04 and solve for <em>t</em> :

$t = \dfrac{\ln(5)}{0.04} \approx 40.24 \approx \boxed{40}$
