Answer:
The18th term of the given sequence is -128
Explanation:
To find the 18th term of the sequence:
42, 32, 22, 12, ..., we need to find the nth term of the sequence first.
The nth term of a sequence is given be the formula:

Where a is the first term, and d is the common difference.
Here, a = 42, d = 32 - 42 = -10

To find the 18th terem, substitute n = 18 into the nth term

50x513 is 25,650, 25,650x2 is 51,300
Answer:
<18 = 40
Step-by-step explanation:
<3 = <19 since they are alternate exterior angles and alternate exterior angles are equal for parallel lines cut by a transversal
<19 = 140
<19+<18 = 180 since they form a straight line
140 + <18 = 180
Subtract 140 from each side
140-140 + <18 = 180-140
<18 = 40
