Can someone solve this problem please

Let N0, N1, N2, N3, N4, N5, N6, N7 be an (unknown) list of eight whole numbers with the property that

N0 = the number of times 0 occurs in the list.

N1 = the number of times 1 occurs in the list,

And so on.

Thus each Ni counts the number of times the number ‘i’ occurs in the list.

1. The N0 is ………..

1] 0 2] 1 3] 2 4] 4



2. How many of N4, N5, N6 and N7 can be non-zero? (1mark)

1] 0 2] 1 3] 2 4] 3



3.. How many times does 1 occur? (1mark)

1] 0 2] 1 3] 2 4] 3



4. Which of the following statements can be true? (2marks)

(i) 2 4 N = N (ii) 0 3 N = N

(iii) 3 4 5 6 N = N = N = N (iv) 3 5 6 7 N = N = N = N

1] 1 and 3 only 2] 2 and 4 only

3] 1 and 4 only 4] 2 and 3 only.

The sequence is 42101000

N0= 4
N1=2
N2=1
N3=0
N4=1
N5=0
N6=0
N7=0

So the ans are,

1.4
2.option 2
3.Option 3

I can't understand the above q.Can someone please help me with this.

hi, its not that tough if the series is going to infinite.
take
k=sq(1+sq(2+sq(3+.........
now for a infinite series u can write
k=sq(1+k)
now try and solve it.
the answers are (1+sqrt(5))/2 and (1-sqrt(5))/2

hope u get the logic.
