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
GH: chord
M: point of tangency
MJ: diameter
J: center
MH: radius
GH: secant
(f-g)(x) = 4x²-2x-12 which,evaluated at x=4, gives 64-8-12=44
Answer: 5x3 + x2 - 2x + 5
Make sure to combine like terms and watch out for if it’s subtraction or addition.
