Answer:
![a_n=50+(n-1)30](https://tex.z-dn.net/?f=a_n%3D50%2B%28n-1%2930)
Step-by-step explanation:
Given series is,
50,80,110....
First term, a = 50
Common difference, d = 80-50 = 30
We need to find the nth term of the given sequence.
The nth term of an AP is given by :
![a_n=a+(n-1)d](https://tex.z-dn.net/?f=a_n%3Da%2B%28n-1%29d)
Put a = 50 and d = 30 in the above formula
![a_n=50+(n-1)30](https://tex.z-dn.net/?f=a_n%3D50%2B%28n-1%2930)
Hence, the nth term of the sequence is
.
Answer:
a is 5 because there is no other one digit numbe that is a common multiple of 5
Step-by-step explanation:
Answer:The second one to the right is 50 because 5 times 5 is 25 and the other is 5 times 5 to and 25 plus 25 is 50.The 2 one on the right is 40 is you multiply the length times width which is the area of a rectangle and square so do that for all of them and you find the answer for x by determining whats the length and width based on the known answers already
Step-by-step explanation:
Hope this helps :D
