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
This in the simplest form will be 2/15. You cannot divide this answer by anything which means it is in its simplest form!

#1

- The limit tends to 0
- Hence c=0

- Here limit tends to 1
- Hence c=1

- Here x tends to infty.
- c=infty
For the fourth one limit also tends to zero
The answer is 750000000000
