The explicit formula of the sequence is given by a_n = -4n(n-1).
We have to find the first five terms of the sequence.
The first term:
The second term:
The third sum:
The fourth term:
The fifth term:
Thus, option D is correct.
Answer: Teo is 6 years old and Sara is 1 year old.
Step-by-step explanation:
This can be translated as:
Teo's age from 2 years ago was equal to Sara's age in 3 years.
In 2 years from now, Sara will have half the age of Leo.
we want to find the age of Sara and Leo.
we can write Teo's age as T, and Sara's age as S.
Then we have that:
T - 2 = S + 3
S + 2 = T/2
first, we must isolate one of the variables in one of the equations, let's isolate T in the first equation:
T = S + 3 + 2 = S + 5
now, we can replace it in the second equation:
S + 2 = T/2 = (S + 5)/2
2S + 4 = S + 5
2S - S = 5 - 4
S = 1
Then Sara is one year old, and the age of Teo is:
T - 2 = 1 + 3
T = 4 + 2 = 6
Teo is 6 years old.
