What is the missing value in (6,10,14,\Box,22,\ldots)?
Answer and explanation
Correct answer: 18
This is an arithmetic progression because the differences 10-6 and 14-10 are both 4. Therefore, the term after 14 is 14+4=18. Checking further, 18+4=22. Option 16 would give a difference of 2 from 14, so it is not correct. Exam tip: In an AP missing-term question, verify that the common difference is the same on both sides of the blank.
