I am looking at an old IBM PAT (circa 1965) and am stumped by a number sequence question. This is it:
Identify the pattern in the following sequences and select the option which indicates the next element in the sequence.
6 10 7 14 14 18
- a) 14
- b) 15
- c) 16
- d) 18
- e) 21
If anyone can identify the pattern and the correct answer, I would be very interested to hear.
