1.1.1 Series, analogies and classification notes
7 notes, in reading order.
- 1.1.1.1Number series: patterns, missing and wrong terms
Every number series hides one rule (a difference, a ratio, a power or a mix); find it from the first few terms, test it on all terms, then apply it to the blank, the next term or the term that breaks it.
Advanced · 7 min · Full course - 1.1.1.2Letter and alphanumeric series
Turn every letter into its position number (A = 1 … Z = 26), solve the series as a number series, and turn the answer back into a letter; arrangement questions are solved by counting positions from the correct end.
Advanced · 6 min · Full course - 1.1.1.3Analogies: number, letter and word
An analogy "A : B :: C : ?" asks you to name the exact relationship between A and B, in that direction, and apply the same relationship to C.
Advanced · 7 min · Full course - 1.1.1.4Classification: odd one out
In classification, all options but one share a property; find the most specific common property and the item that lacks it is the answer.
Advanced · 6 min · Full course - 1.1.1.5Missing numbers in figures and matrices
A missing-number figure is a number series laid out in space: decide first which numbers belong together (a row, a column, opposite sectors, the corners and the centre), find the one rule that links every such group, then apply it to the group with the blank.
Advanced · 8 min · Full course - 1.1.1.6Letter repetition series and alphabet position tricks
Blank-filling letter series repeat a short unit (sometimes rotated, mirrored or growing), so find the unit from the length of the series; alphabet questions are pure position arithmetic, so turn every letter into its number before you count.
Advanced · 8 min · Full course - 1.1.1.7Word formation, dictionary order and meaningful-word arrangement
Dictionary order compares words letter by letter from the left, word formation is a letter-count check against the given word, and meaningful-word questions are solved by listing the selected letters first and only then looking for words.
