Question

Describe the pattern in the numbers. Write the next number in the pattern.
7,  3.5,  1.75,  0.875, …

hintHint:

A sequence of numbers which has a common difference between any two consecutive numbers is called an arithmetic progression (A.P.). The arithmetic progression general form is given by a, a + d, a + 2d, a + 3d, . . .. Hence, the formula to find the nth term is:
an = a + (n – 1) × d

The correct answer is: 7 , 3.5 , 1.75 , 0.875 , 0.4375


    We have given a pattern

    7,  3.5,  1.75,  0.875, …
    We have to find the next term of the given pattern
    First term is 7 and second is 3.5 and third is 0.875
    On analysis we get that , the next term is half of the previous term
    Therefore the next term will be
    Fourth term = 0.875 / 2 = 0.4375
    Therefore, the pattern will be 7 , 3.5 , 1.75 , 0.875 , 0.4375 , …
