Answer:
A) in the relationship the rates of go cost course is given by d=2
So Since, the cost of
1. Lap= 2 $
2.Lap= 2 x 2 = 4 $
3.Lap= 4 + 2 = 6 $
4.Lap= 6 + 2 = 8 $
B) The (n) term of the sequence 2,4,6,8,... with, a,= 2,d= 2 is
a(n) = a,1 + (n - 1)d Write the formula
a(n) = 2 + (n - 1)2 Substitute values
a(n) = 2 + 2,n-2 Simplify
a(n) = 2n
Therefore, the (n) term of the sequence is a(n) = 2(n)
Step-by-step explanation:
I hope this helps at least for A and B
