Answer:
The first 5 terms of the sequence are 2, 4, 8, 16 and 32.
Step-by-step explanation:
Given:
= 2
= 2
-----------------(i)
To get the first 5 terms of the sequence, substitute in turn, n = 1, 2, 3, 4, 5 into equation (i).
The first term (when n = 1) has been given as:
= 2
The second term (when n = 2) is given as:
= 2
= 2
(but
= 2 )
=>
= 2(2)
=>
= 4
The third term (when n = 3) is given as:
= 2
= 2
(but
= 4 )
=>
= 2(4)
=>
= 8
The fourth term (when n = 4) is given as:
= 2
= 2
(but
= 8 )
=>
= 2(8)
=>
= 16
The fifth term (when n = 5) is given as:
= 2
= 2
(but
= 16 )
=>
= 2(16)
=>
= 32
Therefore, the first 5 terms of the sequence are 2, 4, 8, 16 and 32.
Answer:
c This is the direct variation
Step-by-step explanation:
The equation for direct variation is y= kx
Solving this for k
y/x =k
So y/x must be a constant
a. 9/3 =3
2/7 does not =3 so this is not a direct variation
b 1/2 = .5
-3/6 = -.5
This is not the same so this is not a direct variation
c. 27/9 =3
18/6 =3
9/3 =3
This is a direct variation with a constant of 3
d 5/-7 = -5/7
1/-3 = -1/3
This is not the same so this is not a direct variation
