Question

Find the missing term in the series given below.
23,7, 23,9,23, ?,23

Answer 1

Answer:

The pattern followed here is,

1 + (7 × 1) = 8;

8 + (7 × 1) = 15;

15 + (7 × 2) = 29;

29 + (7 × 2) = 43;

43 + (7 × 3) = 64;

64 + (7 × 3) = 85;

85 + (7 × 4) = 113

Hence, 85 is the correct answer.

Answer 2

Answer:

The missing number is 11.

Step-by-step explanation:

Number series:

Number series refers to the series of numbers which follows a pattern.

Types of series:

• Arithmetic series

• Geometric series

• Arithmetico-Geometric series

• Division series

• Difference series

• Square or cube series

• Mixed series

       Given series is

           23,7,23,9,23,-----,23

     Alternatively we can see there are two series.

     First sequence have a constant number 23.

     So, the first series is constant series.

     Second sequence have numbers

                 7,9,-----

     we can observe the difference between the numbers is 2

     So, add 2 to 9 then we get the next number as 11.

        Hence, The missing number in the series  is 11.

               Series is 23,7,23,9,23,11,23
