Answer:
f(12) = 28
Step-by-step explanation:
All you have to do is plug in 12 as x.
f(12) = 2(12) + 4
= 24 +4
= 28
And you're done! :)
It has been given that the Fibonacci sequence starts as 0, 1 , 1 , 2 , 3 , 5 , 8
We can see that every term is equal to the sum of the previous two terms
We already have 7 terms, so to determine the next three terms:
term 8 = t₈ = t₇ + t₆ = 8 + 5 = 13
term 9 = t₉ = t₈ + t₇ = 13 + 8 = 21
term 9 = t₁₀ = t₉ + t₈ = 21 + 13 = 34
Hence, the next three terms are 13, 21 and 34. So the correct option is B
Equation:
x/3 = x/8 + 2/3

Multiply thru by 24 to get:
8x = 3x + 16
5x = 16
x = 3 1/5
========
You want to get the t to itself so you would add 13 to 13 which would give you 26, t=26
