What is the sum of the finite arithmetic series 4+8+12+16...+76
Alexxx [7]
A(n)=4+4(n-1)

a(n)=4+4n-4

a(n)=4n

76=4n

n=19

The sum of any arithmetic sequence (series are infinite) is:

(a+a(n))(n/2)

The average of the first and last terms times the number of terms, in this case we found that n=19 so:

19(4+76)/2=760

Gabrielle's age is three times Mikhail's age. The sum of their ages is 56, what is their age?
My name is Ann [436]
G=3M

G+M=56

-------------------------------------------

3M+M=56

4M=56

M=56/4=14

---------------------------------------------

G+14=56

G=42

---------------------------------------------

So Gabriel is 42 and Mikhail is 14.
