Question

Which number will complete the following number series 7,16,21,70,79,?​

Answer 1

Given: The series 7, 16, 21, 70, 79, ?​

To find: Which number will complete the following number series ?

Solution:

• Now we have given the series:

                 7, 16, 21, 70, 79, ?

• Now the logic behind is:

                 7 + 3² = 7 + 9 = 16

                 ​ 16 + 5 = 21

                 21 + 7² = 70

                 70 + 9 = 79

• So 3² , 5 , 7² , 9 is added to the term.

• Now the term to be added in 79 will be 11², so:

                 79 + 11² = 79 + 121 = 200

Answer:

           So the next term will be 200.
