Blizzard [7]

1 * 7 + 2 * 1 + 3 * 3 + 4 * 2 + 5 * 2 =

7 + 2 + 9 + 8 + 10 =

Now we need to divide 36 by the total frequency: 7+1+3+2+2=15

36 / 15 = 2.4

Find the third fourth and fifth terms of the sequence defined by a1=1, a2=3, and a n =(-1)n a n-2 for n>3

Maslowich

We have been given that

$a_1=1\\ a_2=3\\
a_ n =(-1)^n a _{n-2} \text{ for } n>3$

In order to find the third term, we substitute n=3

$a_ 3 =(-1)^3a _{(3-2)}\\
\\
a_ 3 =(-1)^3 a _{1}$

Substituting the given value of $a_1$

$a_ 3 =(-1)^3 \times 1\\
\\
a_3=-1\times 1\\
\\
a_3=-1$

Similarly, we can find the fourth term by plugging n=4

$a_ 4 =(-1)^4a _{(4-2)}\\
\\
a_ 4 =(-1)^4 a _{2}\\
\\
a_4= 1\times 3\\
\\
a_4=3$

Therefore, the third term is -1

And the fourth term is 3
