Each question shows a series of letters that follows a hidden rule. Work out how each letter (or pair of letters) changes step by step, then pick the option, A to E, that carries on the pattern. Try to keep to roughly a minute per question, and mark your choice on the answer sheet.
Worked example. Find the letter that continues the series: F, I, L, O, ( ? ) Answer: R. The letters go F, I, L, O, each 3 places further on than the one before (F+3=I, I+3=L, L+3=O), so the next letter is 3 further on than O, which is R.
