Answer: 31 - 3n
Step-by-step explanation:
step one:
25 - 28 = -3
22 - 25 = -3
19 - 22 = -3
d = -3
Step two:
An = a1 + (n-1) d
= 28 + (n-1) -3
= 28 - 3n + 3
= 31 - 3n
a1= 28 d = 3
Answer:
a = 0, i, -i, 1, -1
Step-by-step explanation:
What we're basically looking for here is a number, that when multiplied by itself any amount of times, will get us with the same number.
We know that 0 times and number will be 0, so 0 works.
1 times any number will be 1, and -1 would also work as -1² = 1.
i would also work as it represents the square root of a negative, and -i would also work.
Hope this helped!
