What is the next number in this sequence: 1, 8, 15, 22, 29, __________ ?
| 30 | |
| 39 | |
| 41 | |
| 36 |
The equation for this sequence is:
an = an-1 + 7
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 + 7
a6 = 29 + 7
a6 = 36
Find the average of the following numbers: 14, 8, 12, 10.
| 15 | |
| 6 | |
| 9 | |
| 11 |
To find the average of these 4 numbers add them together then divide by 4:
\( \frac{14 + 8 + 12 + 10}{4} \) = \( \frac{44}{4} \) = 11
What is the next number in this sequence: 1, 3, 7, 13, 21, __________ ?
| 31 | |
| 27 | |
| 36 | |
| 23 |
The equation for this sequence is:
an = an-1 + 2(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 + 2(6 - 1)
a6 = 21 + 2(5)
a6 = 31
If there were a total of 250 raffle tickets sold and you bought 5 tickets, what's the probability that you'll win the raffle?
| 18% | |
| 19% | |
| 5% | |
| 2% |
You have 5 out of the total of 250 raffle tickets sold so you have a (\( \frac{5}{250} \)) x 100 = \( \frac{5 \times 100}{250} \) = \( \frac{500}{250} \) = 2% chance to win the raffle.
