Question

Find the missing number 23, 46, 70, 98, 135 , ....

• A. 155
• B. 166
• C. 177
• D. 188

Answer 1

Answer:

D. 188

The pattern of the sequence appears to be an increase of 23, 24, 28, 37, ... (adding 1, 4, 9, 16, ... to the previous difference). Let's analyze the differences: 46 - 23 = 23 70 - 46 = 24 98 - 70 = 28 135 - 98 = 37 The next difference should be 53 ( adding 16 to 37), so : 135 + 53 = 188
