1).Write the first five terms of the sequence whose nth term is -10n-1.

1ST_
2ND_
3RD_
4HT_
5TH_

for first, let n = 1, so -10-1 = -11

etc.

now you try the rest

To find the first five terms of the sequence -10n-1, we can substitute the values of n from 1 to 5 into the given formula.

1. For the 1st term (n = 1):
-10(1) - 1 = -10 - 1 = -11

2. For the 2nd term (n = 2):
-10(2) - 1 = -20 - 1 = -21

3. For the 3rd term (n = 3):
-10(3) - 1 = -30 - 1 = -31

4. For the 4th term (n = 4):
-10(4) - 1 = -40 - 1 = -41

5. For the 5th term (n = 5):
-10(5) - 1 = -50 - 1 = -51

So, the first five terms of the sequence are:
1st term: -11
2nd term: -21
3rd term: -31
4th term: -41
5th term: -51
