Which term of the AP 21, 18, 15 ...... is -81 ?​
amid [387]

Given AP is 21 ,18,15,...

First term = 21

Common difference = 18-21 = -3

Let an = -81

We know that

an = a+(n-1)d

⇛21+(n-1)(-3) = -81

⇛ 21-3n+3 = -81

⇛24-3n = -81

⇛ 24+81 = 3n

⇛ 105= 3n

⇛ n = 105/3

⇛ n = 35

35th term of the AP is -81.

n200080 [17]

Answer:

C. Dividing by 4 is the inverse of multiplying by 4.

Step-by-step explanation:

We have been given 4 options. We are asked to choose the option that represents inverse relationship.

We know that inverse of addition is subtraction and vice versa.

We also know that inverse of multiplication is division and inverse of division is multiplication.

Upon looking at our given choices, we can see that option C is the correct choice because we are multiplying and dividing by same number 4. Upon dividing and multiplying a quantity by 4, we will get the same quantity.

\frac{4\cdot a}{4}=a

Therefore, dividing by 4 is the inverse of multiplying by 4.
