Answer:
Yes the sequence is arithmetic
The common difference is 6
Step-by-step explanation:
Determine whether the following sequences are arithmetic. If so, identify the common difference.
9, 15, 21, 27, ...
The sequence given in the above question is arithmetic because it follows the formula
Un = a + (n -1)d
Where
a= First term
n = Number of terms
d = Common difference
The common difference is calculated as the
Second term - First term
15 - 9
= 6
or the Third term - Second term
21 - 15
= 6
or the Fourth term - Third term
= 27 - 21
= 6
Therefore, the Common difference = 6

1.
52 is 32% of what number
52 = .32x
<u>÷ .32 </u> <u>÷ .32 </u>
162.5 = x
2.
what number is 70% of 373
x = .70 × 373
x = 261.1
3.
84 is what percent of 732
84 = x ÷ 100 × 732
<u>÷732 </u> <u> ÷ 732 </u>
0.115 = x ÷ 100
<u>×100 </u> <u> × 100 </u>
11.5% = x
