The answer is a) 35 because if you set 21/49 and 15/h equal to eachother and cross multiply it should lead you to 21(h) = 15(49) which then equals 21h = 735 and if you divide 21 on both sides you should get h = 35

Answer:
see below
Step-by-step explanation:
-33, -27, -21, -15,....
-33 +6 = -27
-27+6 = -21
-21+6 = -15
This is an arithmetic sequence
The common difference is +6
explicit formula
an=a1+(n-1)d where n is the term number and d is the common difference
an = -33 + ( n-1) 6
an = -33 +6n -6
an = -39+6n
recursive formula
an+1 = an +6
10th term
n =10
a10 = -39+6*10
= -39+60
=21
sum formula

The sum will diverge since we are adding infinite numbers
20.89 times .25 to get 5.2225 so there would be $ 5.22 off so you would get 15.67
