Answer 2

Given:

Five series -

(i) 5, 20, 10, 30, 15, 40,  

(ii) 1, 3, 5, 7, 11,

(iii) 5, 8, 11, 14, 17,

(iv) 6, 95, 7, 90, 8, 85,  

(v) 1, 5, 25, 125

To find:

Complete the pattern

Solution:

(i) 5, 20, 10, 30, 15, 40 -

The pattern is following the pattern of adding +5 to every number, thus -

5, 20, 10, 30, 15, 40, 20, 50, 25

(ii) 1, 3, 5, 7, 11,

The pattern is following the pattern of odd numbers, thus -

1, 3, 5, 7, 11, 13, 17, 19

(iii) 5, 8, 11, 14, 17,

The pattern  is following the pattern of + 3 to every number, thus -

5, 8, 11, 14, 17, 20, 23, 26

(iv) 6, 95, 7, 90, 8, 85,

The pattern is following the pattern of + 1 to first number and + 5 to second number, thus -

6, 95, 7, 90, 8, 85, 9, 80, 10

(v) 1, 5, 25, 125,

The pattern  is following the cube of numbers, thus -

1, 5, 25, 125, 625, 3125, 15625
