Answer:
= - 5n - 2
Step-by-step explanation:
There is a common difference between consecutive terms, that is
- 12 - (- 7) = - 17 - (- 12) = - 5
This indicates the sequence is arithmetic with n th term
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference
Here a₁ = - 7 and d = - 5, then
= - 7 - 5(n - 1) = - 7 - 5n + 5 = - 5n - 2
Answer:
16,-8
Step-by-step explanation:
jk=12
j lies at 4
k lies at 4+12=16
or k lies at 4-12=-8

Answer:
-5^11
Step-by-step explanation:
The container has a total of 41 possible numbers from which to draw, and so each one as a probability of 
of being drawn.
Most of these numbers are even (21 of them) and
20 of these numbers are greater than 30, so
and among these, exactly half are even, so that
So we have
