Expression in $n^{th}$ term is T_n =2(6-n)

Step-by-step explanation:

Arithmetic sequence 10,8,6,4,.....

first term a = 10

second term = 8

number of terms = n

common difference d = Second term - First term = $8-10 \ =\ -2$

Now by using Arithmetic Progression Formula which states

T_n = a+(n-1)d

Substituting given values in the above expression we get

$T_n= 10+((n-1)\times-2})= 10-2n+2= 12-2n= 2(6-n)$

The Answer Is 7,000 because the thousand is 6,605.then look at the next number its a 6 REMEMBER:1-5 you leave the oringinal number and the rest zeros and 6-9 add the number.Thats how you get 7,000
