What are the first four terms of the sequence represented by the expression (n -2 )
-3
1. -5, -2,-,1,4
2.-4,-3,0,5
3. -3,0,3,6
4. -2,0,2,4
1. -5, -2, 1, 4
explain why
To find the first four terms of the sequence represented by the expression (n - 2) - 3, we need to substitute the values of n from 1 to 4 in the expression and simplify it.
For n = 1, the expression becomes (1 - 2) - 3 = -4.
For n = 2, the expression becomes (2 - 2) - 3 = -3.
For n = 3, the expression becomes (3 - 2) - 3 = -2.
For n = 4, the expression becomes (4 - 2) - 3 = -1.
Therefore, the first four terms of the sequence are -4, -3, -2, and -1. However, if we simplify the given expression differently, we can write it as n - 5, which means we subtract 5 from each value of n.
For n = 1, the sequence becomes 1 - 5 = -4.
For n = 2, the sequence becomes 2 - 5 = -3.
For n = 3, the sequence becomes 3 - 5 = -2.
For n = 4, the sequence becomes 4 - 5 = -1.
Hence, the first four terms of the sequence represented by the expression (n - 2) - 3 are -4, -3, -2, and -1.
To find the first four terms of the sequence represented by the expression (n -2), we need to substitute the values of n from 1 to 4 into the expression.
1. (1 - 2) = -1
2. (2 - 2) = 0
3. (3 - 2) = 1
4. (4 - 2) = 2
Therefore, the first four terms are -1, 0, 1, and 2. Thus, the correct answer is option 4. -2, 0, 2, 4.
