What is the next number in this sequence: 1, 5, 13, 25, 41, __________ ?
| 65 | |
| 62 | |
| 59 | |

The equation for this sequence is:
an = an-1 + 4(n - 1)
where n is the term's order in the sequence, an is the value of the term, and an-1 is the value of the term before an. This makes the next number:
a6 = a5 + 4(6 - 1)
a6 = 41 + 4(5)
a6 = 61

Roger loaned Jennifer $1,000 at an annual interest rate of 5%. If no payments are made, what is the total amount owed at the end of the first year?
| $1,050 | |
| $1,010 | |
| $1,040 | |
| $1,080 |
The yearly interest charged on this loan is the annual interest rate multiplied by the amount borrowed:
interest = annual interest rate x loan amount
i = (\( \frac{6}{100} \)) x $1,000
i = 0.05 x $1,000
No payments were made so the total amount due is the original amount + the accumulated interest:
total = $1,000 + $5013 members of a bridal party need transported to a wedding reception but there are only 4 2-passenger taxis available to take them. How many will need to find other transportation?
