Prmoise for brinliest plzzz answer if u know this !
what are the first four terms of the sequence represented by the expression n(n – 1) – 5?
a.)–7, –5, –3, 1
b.) –5, –10, –15, –20
c.00, 2, 6, 12
d.)–5, –3, 1, 7

1st term: n = 1

apply the value 1 to n in the equation:

1(1-1) - 5

1(0) - 5

0 - 5

- 5

Second term n = 2

2(2 - 1) - 5

2 (1) - 5

2 - 5

-3

Since we know the 1st term is -5 in the sequence and the second is -3, we can assume the answer is D. -5, -3, etc

hi there!

first we need to find out how much they are adding to each number to make the next number.

ex: 4 + 4 = 8, 8 + 8 = 16, and so on.

so continuing with 32,

32 + 32 = 64

64 + 64 = 128

128 + 128 = 256

256 + 256 = 512

4, 8, 16, 32, 64, 128, 256, 512

the 8th term of the sequence will be 512

hope this ! ~

hope this !

let me know
