Answer:
Ana is correct
Step-by-step explanation:
Given
[tex]Sequence:\ -10, -4, 2,8[/tex]
[tex]Carlos; f(n) = -10 + 6n[/tex]
[tex]Ana; f(n) = -10 + 6(n-1)[/tex]
Required
Determine who is right?
To do this, we simply test each sequence.
For Carlos:
When n = 1
[tex]f(1) = -10 + 6 * 1 = -10 + 6 = -4[/tex]
When n = 2
[tex]f(2) = -10 + 6 * 2 = -10 + 12 = 2[/tex]
This is incorrect because the first and second term of the sequence are -10 and -4 not -4 and 2
For Ana:
When n = 1
[tex]f(1) = -10 + 6(1-1) = -10 + 6*0 = -10 + 0 = -10[/tex]
When n = 2
[tex]f(2) = -10 + 6(2-1) = -10 + 6*1 = -10 + 6 = -4[/tex]
When n=3
[tex]f(3) = -10 + 6(3-1) = -10 + 6*2 = -10 + 12 = 2[/tex]
When n = 4
[tex]f(4) = -10 + 6(4-1) = -10 + 6*3 = -10 + 18 = 8[/tex]
This is correct.
Hence, Ana is correct
