Answer:
nth term = 5n - 9
Step-by-step explanation:
This is an arithmetic progression. Its formula is:
In this case, a1 is - 4 and the rate is:
1 - (- 4) = 5
Then, r = 5.
Changing It:
an = nth term
I hope I've helped you.
this the arithmetic sequence when the common dif is : 6-1 = 1-(-4) =5 and the first term is -4
the nth term is An = A1 +(n-1)d
A1 = -4 and d = 5
so : An = -4 +(n-1)5 = -4 +5n -5
An = 5n - 9

B is the answer because none of the others will be right and b is the one you should always do when to solve a rea word problem
red balls = 5
blue balls = 5
total balls = 5 blue+5 red
= 10
