hope this will help j please understand tha solution

Answer 2

Answer:

• The blank shall be replaced by the number 104.

Step-by-step explanation:

• 5,65,6,78,7,91,8,?,9,11

It can be clearly observed from the pattern that, the difference between the numbers (5 and 6), (6 and 7), (7 and 8), and (8 and 9) is 1.

Similarly, the difference between (65 and 78), and (78 and 91) is found to be 13.

Thus, the difference between the numbers (91 and ?) should also be 13. So, the number will be, 91+13 = 104.

This can be verified by further adding 13 to 104, to get 117.

Hope you're helped. please mark me as brainliest.
