Answer:
two is the number
Step-by-step explanation:
i think that
q + d = 80
.25q + .10d = 14.45
q. + d= 80
25q + 10d = 1445
-10q. - 10d = -800
25q + 10d = 1445
15q. = 645
q = 43 quarters
43 + d = 80
d= 37 dimes
The given in the problem above is an arithmetic sequence with the first term equal to 4 and the common difference is 5. To determine the number of seats on row 23, use the formula,
an = a1 + (n - 1) d
Solving for the 23rd term,
an = 4 + (22) 5 = 114 seats
Therefore, the answer is there are 114 seats on the 23rd row.
