What is the next number in this sequence: 1, 8, 15, 22, 29, __________ ?
| 33 | |
| 36 | |
| 35 | |
| 30 |
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
What is the next number in this sequence: 1, 5, 13, 25, 41, __________ ?
| 65 | |
| 69 | |
| 61 | |
| 56 |
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
Find the average of the following numbers: 15, 9, 16, 8.
| 12 | |
| 10 | |
| 15 | |
| 17 |
To find the average of these 4 numbers add them together then divide by 4:
\( \frac{15 + 9 + 16 + 8}{4} \) = \( \frac{48}{4} \) = 12
If there were a total of 350 raffle tickets sold and you bought 28 tickets, what's the probability that you'll win the raffle?
| 16% | |
| 18% | |
| 7% | |
| 8% |
You have 28 out of the total of 350 raffle tickets sold so you have a (\( \frac{28}{350} \)) x 100 = \( \frac{28 \times 100}{350} \) = \( \frac{2800}{350} \) = 8% chance to win the raffle.
