In an explicit formula, n represents any term number and a(n) represents the value of the n-th term. Therefore, in order to find the fifth term, we simply solve for a(n) when n = 5. Plugging that value into the equation gives us a(5)=6(5)-4, or a(5) = 26. The fifth term is of the sequence is 26.

Alja [10]

Answer:

When m = 6, 5m - 4 = 26.

Step-by-step explanation:

Substitute:

$f(6)=5(6)-4$

Multiply:

$f(6)= 30-4$

Subtract:

$f(6)= 26$

A town's population is 14,280, and it is increasing by 160 people every year. A nearby town has a population of 24,000, and it i

fgiga [73]

Answer:

27 years

Step-by-step explanation:

Given that :

Town A:

Initial population = 14280

Rate = increase by 160 per year

Let t = time in years

Population is thus :

14280 + 160t - - - (1)

Town B:

Initial population = 24000

Rate = decrease by 200 per year

P = 24000 - 200t - - - (2)

Equate both equations :

14280 + 160t = 24000 - 200t

160t + 200t = 24000 - 14280

360t = 9720

t = 9720 / 360

t = 27
