I'd personally go with A and C, The rest don't make too much sense. Don't count on my answer just yet though.

1 2 3 4 .... 1002 what is the sum of the sequence

Reika [66]

<span>As far as i know it is related to Gauss.
Write the sequences forward and backward first.

1 +2 +3 +.....+1002
1002+1001+1000+.....+1
--------------------------------------... Adding them
1003+1003+......(1002 times)
=1002x1003
But this contains the series twice.
So, the sum is = 1002x1003/2=501x1003=502503. answer</span>

The amount of money in a savings account after t years is represented by the function f(t)=500(1.015)t.

Sauron [17]

$\bf \qquad \textit{Amount for Exponential Growth}\\\\
A=I(1 + r)^t\qquad 
\begin{cases}
A=\textit{accumulated amount}\\
I=\textit{initial amount}\\
r=rate\to r\%\to \frac{r}{100}\\
t=\textit{elapsed time}\\
\end{cases}
\\\\\\
f(t)=\stackrel{\stackrel{I}{\downarrow }}{500}(1.015)^t$
