First we can add 150 + 50 = 200.
Then we can subtract 75 from that to get 125.
Now our equation is 125 + ? = 0.
What we have to do is add -125 to get zero.
So ? = -125.
Hope this helps!

Evaluate the summation of 3 times negative 2 to the n minus 1 power, from n equals 1 to 5..

Gnom [1K]

For n = [1,2,3,4,5] you can evaluate the series as follows:

$3( -2)^{1-1} +3( -2)^{2-1} +3( -2)^{3-1} +3( -2)^{4-1}+3( -2)^{5-1}$
= 3 + (-6) + (12) + (-24) + (48)
= 63 - 30
= 33

Suppose the population in a town average growth rate of 18% if there are 15500 people now living in town in about how many years

madam [21]

This is just a matter of solving for $x$ in the given equation.

$30000=15500\times1.18^x$
$\implies 1.935=1.18^x$
$\implies \log_{1.18}(1.935)=\log_{1.18}(1.18^x)$
$\implies 3.988=x\implies x\approx 4\text{ years}$
