7f lenghtg is 29.2
Step-by-step explanation:
If an items weight is 0 it would be like a peice of paper or cotten ball. when a cotten ball is weighed it does not affect anything. as when a peice of paper is wieghed it moves its meater 1 inch.
Step-by-step explanation:
To find the formula for the nth term ,
First , find the common difference or common ratio.
Common difference =
![T_2-T_1 \\ - 2 - 3 \\ = - 5](https://tex.z-dn.net/?f=T_2-T_1%20%5C%5C%20%20-%202%20-%203%20%5C%5C%20%20%3D%20%20-%205)
Common ratio =
![T_2/T_1 \\ \frac{ - 2}{3}](https://tex.z-dn.net/?f=T_2%2FT_1%20%5C%5C%20%20%5Cfrac%7B%20-%202%7D%7B3%7D%20)
The common difference applies to the other given numbers for example :
![T_3- T_2 = - 7 - ( - 2) \\ = - 7 + 2 = - 5](https://tex.z-dn.net/?f=T_3-%20T_2%20%20%3D%20%20-%207%20-%20%28%20-%202%29%20%5C%5C%20%20%3D%20%20-%207%20%2B%202%20%3D%20%20-%205)
this proves that it is an arithmetic sequence and the given formula for the nth term of an arithmetic sequence is
T_n =a(n-1)d
Where n = no of terms
a= first term
d= common difference
