Answer:

-6n+20

Step-by-step explanation:

The given  term of sequece is  14, 8, 2, -4, …,

Here the first term is 14 and then the terms are decreasing by 6 each time  because 14-8=8-2=...=6

As we know that the nth term of the sequence is given by the formula

t_n=a+(n-1)d\\\text{Substitute the values we get}\\t_n=14+(n-1)(-6)\\t_n=14-6n+6\\t_n=20-6n\\

If n is a term of the given sequence sequence, then its value is -6n+20

adoni [48]

Answer:

the previous population was 62,000.

Step-by-step explanation:

The current population of a city = 83,700

The population of a city has increased by 35% since it was last measured.

We have to calculate the previous population before increasing 35%.

Let the previous population be p

p +(35% × p) = 83,700

p + 0.35p = 83,700

1.35p = 83,700

p =  

p = 62,000

Therefore, the previous population was 62,000.
