Answer:
Step-by-step explanation:
An = 54 + 3(n-1)
n = 1 ; A1 = 54 + 3*(1-1) = 54 + 3*0 = 54 +0 = 54
n =2 ; A2 = 54 + 3*(2-1) = 54 + 3*1 = 54 + 3 = 57
n =3 ; A3 = 54 + 3*(3-1) = 54 + 3*2 = 54 + 6 = 60
n =4 ; A4 = 54 + 3*(4-1) = 54 + 3*3 = 54 + 9 = 63
Answer:
x<-21
Step-by-step explanation:
x/7<-3
x<-21
Whole numbers are the numbers 0, 1, 2, 3, 4 and so on and negative numbers are not considered whole numbers.
natural numbers are called the counting numbers that are the numbers 1, 2, 3, 4, and so on. they are positive numbers and zero is not considered a natural number as you can see.
integers are all the whole numbers and their opposite (negative) but negative numbers are NOT whole or natural numbers. fractions and decimals are not integers.
rational numbers are numbers that include all the integers, plus all fractions, or terminating decimals and repeating decimals.
irrational numbers are an infinite number of digits to the right of the decimal point, without repeating.
so your answer is integer and rational, hope this helped! :)
