➤Method:

• there are two methods , by which we can solve this question.....

➜ METHOD 1.

• 4 × 2 = 8 ; 8 - 1 = 7

• 7 × 2 = 14 ; 14 - 1 = 13

• 13 × 2 = 26 ; 26 - 1 = 25

• 25 × 2 = 50 ; 50 - 1 = 49

• MISSING TERM = 49 × 2 = 98 ; 98 - 1 = 97

➜ METHOD 2.

• 4 + 3 = 7

• 7 + 6 = 13 ( here 6 is double of 3 , which was added in previous term.)

• 13 + 12 = 25 ( here 12 is double of 6 which was added in previous term.)

• 25 + 24 = 49 (here 24 is the double of 12 which was added in previous term.)

• MISSING TERM = 49 + 48 = 97

Therefore, by both the methods , we get the missing number as = 97

Answer 2

Answer:

4 × 2 = 8 ; 8 - 1 = 7

7 × 2 = 14 ; 14 - 1 = 13

13 × 2 = 26 ; 26 - 1 = 25

25 × 2 = 50 ; 50 - 1 = 49

MISSING TERM = 49 × 2 = 98 ; 98 - 1 = 97

➜ METHOD 2.

4 + 3 = 7

7 + 6 = 13 ( here 6 is double of 3 , which was added in previous term.)

13 + 12 = 25 ( here 12 is double of 6 which was added in previous term.)

25 + 24 = 49 (here 24 is the double of 12 which was added in previous term.)

MISSING TERM = 49 + 48 = 97

Therefore, by both the methods , we get the missing number as = 97
