Answer:
b) -12 , -8 , -4, 0
Step-by-step explanation:
-12 + 4(n - 1)
n means the term
place the values of 1, 2, 3 and 4
-12 + 4(1-1) = -12
-12 + 4(2-1) = -8
-12 + 4(3-1) = -4
-12 + 4(4-1) = 0
hence the answer is
<u>b) -12 , -8 , -4, 0 </u>

Answer:
210
Step-by-step explanation:
Since the condition does not state an opposite, I should assume that the apples are not distinguishable, same as the pears and the oranges.
So we have permutations of 7 fruits with 2 indistinguishable apples, 3 indistinguishable pears and 2 indistinguishable oranges.
The number of distinguishable arrangements is
7 1x2x3x4x5x6x7
--------- ---------------------- = 210
2x3x2 2x6x2
Answer. There are 210 ways to do it.
