Question

1) Write the recursive rule for the sequence.

Answer 1

Answer:

Step-by-step explanation:

i) Recursive rule is

$a_{n+1} =a_n-10$

2) Explicit rule for the sequence is

this is arithmetic sequence with a = -1 and d = 15

Hence

$a_n=-1+15(n-1)\\a_n=15n-16$

3) $P(A and B) = \frac{2}{25} (\frac{5}{6} )\\=\frac{1}{15}$

4) Sample men = total/no of entries

=$\frac{409}{10} =40.9$

=41
