Answer 2

Given:

A series of numbers 120, 143, 168, 195, and 224.

To Find:

The next three terms in the series are?

Solution:

Solution:

The given problem can be solved by developing a common logic between every term.

1. The given series is 120, 143, 168, 195, and 224.

2. The second term in the series is obtained as,

=> Second term = 143 = 120 + 23,

3. The third term of the series is obtained as,

=>Third term = 168 = 143 + 25,

4. The fourth term of the series is obtained as,

=>Fourth term = 195 = 168 + 27,

5. The fifth term of the series is obtained as,

=>Fifth term = 224 = 195 + 29

6. The next three terms can also be determined using the same logic,

=> Sixth term = Fifth term + 31,

=> Sixth term = 224 + 31 = 255,

=> Seventh term = Sixth term + 33,

=> Seventh term = 255 + 33 = 288,

=> Eighth term = Seventh term + 35,

=> Eighth term = 288 + 35 = 323.

7. Therefore, the next three terms are 255, 288, and 323.

Therefore, the next three terms are 255, 288, and 323. Option C is the correct answer.
