If f(1) = 1 and f(n + 1) = 5f(n) + 3 then find the value of f(4).
FrozenT [24]

Answer:

218

Step-by-step explanation:

Because we need f(n) to calculate f(n+1), we have to calculate our values one step at a time. Starting with f(1) = 1,

f(2) = 5(f(1)) + 3 = 5(1) + 3 = 5+3 = 8

f(3) = 5(8) + 3 = 40 + 3 = 43

f(4) = 5(43) + 3 = 215 + 3 = 218

If you have five red balls and five blue balls in a jar what’s the probability of the first ball being red?
rosijanka [135]

Answer:

red balls = 5

blue balls = 5

total balls = 5 blue+5 red

= 10

p(first \: ball \: being \: red) =  \frac{red \: balls}{total \: balls}

p(first \: ball \: being \: red) =  \frac{5}{10}  =  \frac{1}{2}
