Find the next four terms in the arithmetic sequence. a - 6, a - 2, a + 2, a. a + 6, a + 12, a + 15, a + 18 b. a + 4, a + 10, a + 12, a + 14 c. a + 6, a + 10, a + 14, a + 18 d. a + 4, a + 6, a + 8, a + 10 select the best answer from the choices provided a) a b) b c) c d) d

C: a+6, a+10, a+14, a+18

Step-by-step explanation:

a - 6, a - 2, a + 2, ...

Given is arithmetic sequence

General form of arithmetic sequence is

a , a+d, a+2d , a+3d , a+4d

To get next terms we need to find out 'd'

common difference is 'd'

to find 'd' we subtract first term from second term

a -2  - (a-6)= a-2 -a +6 = +4

d= 4

So we add 4 to get next four terms

a+ 2 is the last term

a+2 +4 = a+6

a+6 + 4= a+10

a+ 10 + 4= a+14

a+14 + 4= a+18

so next four terms are

a+6, a+10, a+14, a+18

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.
