Complete the statement
A sequence is an arrangement of numbers in {0} order according to some {1}. One with a finite number of terms is a {2} sequence.
A sequence is an ordered arrangement following a rule, which is exactly what a number-series question hides. Source: syllabus Maths, Ch 9 Sequences and Series.
