Question

If a , b , c are in Arithmetic Sequences then:

  1. 2a = b + c 
  2. 2c = a + b 
  3. 3b = 2a + 3c 
  4. 2b = a + c

hintHint:

We will find the common diffrence in the given equation and evaluate using the equality.

The correct answer is: 2b = a + c


    STEP  BY STEP SOLUTION
    The given AP is a, b , c
    Common differences are equal arithmetic sequence
    b - a = c - b
    2b = a + c

    City tours rents bicycles for $10 an hour with a maximum daily fee of $100. Show the cost for renting bicycle for 1, 3, 11, and 20 hours.

    The cost of renting a bicycle is $ 100 per day. The maximum fair is $ 100 for any number of hours a day. If we have to find a random number of hrs, we can Multiply the number of hrs by the amount of the rent for that particular hour. That gives the total rent for that particular hour.
    Eg: cost of renting bicycle for 1 hour = $10 x 1 = $10
