Answer:16
w(u(2))
= - 2(2×2 - 1 )^2 - 2
= - 2(4 - 1 )^2 - 2
=-2(3)^2-2
=2×9-2
=18-2
=16
Answer:
three consecutive even integers be n-2,n and n+2. n=44. The three consecutive even integers are 42,44 and 46
Step-by-step explanation:
14-2=12 +4= 16 is the answer to your question
-18 + 10 = -8

Answer:
(a) A sequence is an ordered list of numbers whereas a series is the sum of a list of numbers.
(b) A series is convergent if the sequence of partial sums is a convergent sequence, that is tends to a limit.
A series is divergent if it is not convergent.
Step-by-step explanation:
(b) An example of a divergent series is the arithmetic series 2+ 4+6+8+10+...
The sum keeps increasing without bounds.
An example of a convergent series is 100 + 50, +25 + 12.5 +... a geometric series with common ratio 0.5 whose sum tends to a limit. The limit of this series is a1 / (1 - r) = 100 / (1 - 0.5) = 200.
