Directions: In the following question, a number sequence is given with one term missing. Choose the correct term that will continue the same pattern and replace the question mark in the given sequence.17,20,19,22,21,24,23,?
Correct answer: C. 26
- A. 22
- B. 24
- C. 26
- D. 2
Explanation
In the given sequence 17, 20, 19, 22, 21, 24, 23, ?, the pattern alternates between adding 3 and subtracting 1. Starting from 17, the sequence goes +3 (20), -1 (19), +3 (22), -1 (21), +3 (24), -1 (23). Following this pattern, after 23, we should add 3. Therefore, the next term is 26. The options 22, 24, and 2 do not fit this pattern, as they result from operations that do not match the sequence's rule.

About Evolution
Evolution describes heritable change in populations over generations through variation, natural selection and adaptation. Lamarckism explains inheritance of acquired characteristics, while Darwinism explains selection of favourable inherited variations; these historical explanations must not be confused with the modern genetic account of evolutionary change.
