Arithmetic sequence has a common difference between the terms.
for 1,4,7,10,...
4-1 = 3
7-4 = 3
10-7 = 3
so we do see a common difference between the terms.
Hence, True
Answer: See each one below:
1) Since she is paying for 30% of the cost, we multiply it by 0.3. Then, since it is over the whole year, we divide it by 12.
12304 * 0.3 / 12 = 307.6 B
2) First, we subtract the cost of the 50 deductible, then multiply the amound by 0.2 because he has to pay 20% of the balance.
1060 - 50 = 1010 x 0.2 = 202 A
3) First, we find the total cost of the visits. Mattie has to pay for 40% so times it by 0.4. Then, don't forget to add in the cost of 12 co-pays of $15 each.
3660 * 0.4 = 1464 + 15(12) = 1664 B
R = 3/4
term 1 = 96
*Note that all An are (a subscript n) and A(n-1) are (a subscript n-1).*
An = A(n-1)*r
I’m not sure what you have to find but if your trying to find what x and y equal y = 45 and x = 135
