2/3=n/12 solve the proportion

Natali [406]

Answer: $n=8$

Cross-multiply

$2/3=n/12$

$(2)*(12)=n*(3)$

$24=3n$

Flip the equation

$24=3n---->3n=24$

Divide both sides by 3

$3n/3=24/3$

$24/3=8----> n=8$

What is the sum of the arithmetic sequence 3, 9, 15..., if there are 36 terms?

EastWind [94]

We know that
the formula of the the sum of the arithmetic sequence is
Sum=n*(a1+an)/2

n=36
a1=3
a36=?

find a36
an=a1+(n-1)*d

for n=2 a2=9
9=3+(2-1)*d----> 9=3+d----> d=6
so
for n=36
a36=a1+(36-1)*6----> a36=3+35*6----> a36=213

Sum=n*(a1+an)/2-----> 36*[3+213]/2----> 3888

the answer is
3888
