The explicit equation is

a_n=a+(n-1)d

a is the first term

a = 57

d is the constant difference between each 2 consecutive terms

d = 4

We can Split the Middle Term of this expression to factorise it.

In this technique, if we have to factorise an expression like  

a

x

2

+

b

x

+

c

, we need to think of 2 numbers such that:

N

⋅

N

=

a

⋅

c

=

⋅

=

9

and,

N

N

=

b

=

After trying out a few numbers we get:

N

1

=

9

and  

N

=

A house purchased for $230,000 has lost 6% of its value each year for the last four years. What is the house worth now?
lutik1710 [3]
You can use the compound growth to work this out,

Firstly you need to make a multiplier for -6%;
1-(6/100) = 0.94

The you times the amount of money by 0.94 to the power of 4 because you are working out 4 years:
230000*0.94^4 = 179527.26

The answer is $179527.26,
Hope this helps! :)
