Answer 2

Answer:

numerical pattern--> 5,3,9,7,21

Step-by-step explanation:

Checking all options one by one we get,

Option A) :- 5, 7, 21 , 69

→ 7 - 5 = 2

→ 7 * 3 = 21

→ 21 * 3 = 63 .

Here, pattern is add 2 and than multiply by 3 two times.

So, Option A is not correct.

Option B) :- 5, 3, 4 , 12

→ 5 - 3 = 2

→ 3 + 1 = 4

→ 4 * 3 = 12 .

Here, pattern is subtracts 2 , than add 1, and than multiply by 3 .

So, Option B is not correct.

Option C) :- 5, 9, 14 , 36

→ 9 - 5 = 4

→ 14 - 9 = 5

→ 14 * 3 - 6 = 36 .

Here, pattern is add 4, than add 5, and than multiply by 3 and subtract 6 .

So, Option C is not correct.

Option D) :- 5, 3, 9 , 7, 21

→ 5 - 2 = 3

→ 3 * 3 = 9

→ 9 - 2 = 7

→ 7 * 3 = 21 .
