Answer:
A
Step-by-step explanation:
Given the sequence
1, 9, 17, 25, 33, 41
Note the difference in consecutive terms
9 - 1 = 8
17 - 9 = 8
25 - 17 = 8
33 - 25 = 8
41 - 33 = 8
Since the terms have a common difference d then the sequence is arithmetic
To obtain the next term in the sequence add 8 to the previous term
41 + 8 = 49
49 + 8 = 57
57 + 8 = 65
The next 3 terms are 49, 57, 65
The n th term of an arithmetic sequence is
= a₁ + (n - 1)d
where a₁ is the first term and d the common difference, thus
= 1 + (19 × 8) = 1 + 152 = 153
The required solution is 49, 57, 65 ; 153 → A
X = -2
y = 2
You can get this by setting the two different y's equal to each other and solving for the x value.
Answer:
291 .1
Step-by-step explanation:
80.2 + 91.6 + 123 + 204.7 + x = 790.6
790.6 - 499.5 = 291. 1
