What is the next number in this sequence: 1, 10, 19, 28, 37, __________ ?
| 39 | |
| 47 | |
| 37 | |
| 46 |
The equation for this sequence is:
an = an-1 + 9
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 + 9
a6 = 37 + 9
a6 = 46
The __________ is the smallest positive integer that is a multiple of two or more integers.
least common factor |
|
absolute value |
|

|
greatest common factor |
The least common multiple (LCM) is the smallest positive integer that is a multiple of two or more integers.
What is 5y6 + y6?
| 6y6 | |
| 6y36 | |
| 6y12 | |
| 6y-12 |
To add or subtract terms with exponents, both the base and the exponent must be the same. In this case they are so add the coefficients and retain the base and exponent:
5y6 + 1y6
(5 + 1)y6
6y6
What is (z5)4?
| z | |
| 5z4 | |
| z20 | |
| z9 |
To raise a term with an exponent to another exponent, retain the base and multiply the exponents:
(z5)4What is 8\( \sqrt{5} \) x 6\( \sqrt{6} \)?
| 48\( \sqrt{11} \) | |
| 14\( \sqrt{30} \) | |
| 48\( \sqrt{30} \) | |
| 14\( \sqrt{5} \) |
To multiply terms with radicals, multiply the coefficients and radicands separately:
8\( \sqrt{5} \) x 6\( \sqrt{6} \)
(8 x 6)\( \sqrt{5 \times 6} \)
48\( \sqrt{30} \)
