Question

13, 13, 15, 27, 47, 67, 97, 153, ??​

Answer 1

Answer:

13, 13, 15, 27, 47, 67, 97, 153, 225

Answer 2

Solution :-

Logic :- Difference between first two terms is n² - n and difference between next two term is n² + n . So on .

Explanation :-

→ 13 - 13 = 0 = 1² - 1

→ 15 - 13 = 2 = 2² - 2

→ 27 - 15 = 12 = 3² + 3

→ 47 - 27 = 20 = 4² + 4

→ 67 - 47 = 20 = 5² - 5

→ 97 - 67 = 30 = 6² - 6

→ 153 - 97 = 56 = 7² + 7

therefore, next term will be,

→ 153 + (8² + 8) = 153 + 72 = 225 (Ans.)

Hence, (B) 225 will replace the question mark (?) .
