Answer:

22. 18

23. 10

Step-by-step explanation:

you plug the number for the variable into the equation (3(2)²+6
order of operations say exponents first so you do 2²=4 so you have 3(4)+6
then you multiple 3•4=12 so 12+6
finally you add 12+6=18

plug in the number for the variable so 5–(-5)
so a negative and a minus will make it addition (negative + negative = positive)
do it is 5+5 which equals 10

What is the next term of the following sequence? <br><br><br> 20, 10, 5, 21/2, ...

ycow [4]

Answer:

1 $\frac{1}{4}$

Step-by-step explanation:

Note there is a common ratio between consecutive terms, that is

10 ÷ 20 = 5 ÷ 10 = 2 $\frac{1}{2}$ ÷ 5 = $\frac{1}{2}$

Thus to obtain the next term in the sequence multiply the previous term by $\frac{1}{2}$

2 $\frac{1}{2}$ × $\frac{1}{2}$ = 1 $\frac{1}{4}$
