Question

5) 818, 828, 903, _, __ What is the pattern?

Answer 1

Answer:

1043

Step-by-step explanation:

first DIFFERENCE between 818 and 828 is 10 then the difference between 828 and 903 is 75 and the difference between 10 and 75 is 65 and the sum between 903+65+75= 1043

Answer 2

Given:

818, 828, 903, _, __

To find:

The pattern using which the given series is formed.

Solution:

From given, we have,

First term = 818

Second term = 828

Third term = 903

The difference between the second term and the first term is,

828 - 818 = 10

⇒ 5 × 2 = 10

The difference between the third term and the second term is,

903 - 828 = 75

⇒ 5 × 15 = 75

Therefore, the difference is,

15 - 2 = 13

5 × (15 + 13) = 5 × 28 = 140

The forth term is,

903 + 140 = 1043.

Similarly, the fifth terms is given by,

5 × (28 + 13) = 5 × 41 = 205

1043 + 205 = 1248

818, 828, 903, 1043, 1248.........
