Question

109,74,46,25,11,? What is the next number

Answer 1

Given:

• A series is given 109,74,46,25,11,?

To Find:

• We have to find the pattern and the net number of series.

Solution:

Given series is  109,74,46,25,11,?

Difference between $109 - 74 = 35 = 7\times 5$

                             ⇒       $74- 46 = 28 = 7\times 4$

                             ⇒       $46-25 = 21 = 7\times 3$

                             ⇒       $25-11 = 14 = 7\times 2$

so next number is  ⇒     $11 - 7\times 1 = 4$

Thus,  the next number of the series is $4$

 Series is   109,74,46,25,11,4
