Sequences and Series — JAMB Mathematics Past Questions

Sequences and Series is one topic inside the JAMB Mathematics syllabus, and drilling it on its own is usually faster than revising the whole subject again. Below: which JAMB years have examined it, then real Sequences and Series questions with worked answers.

When JAMB examined Sequences and Series

Sequences and Series questions appear in our bank for the JAMB years below. This is taken from the questions themselves, not from a syllabus outline — so if a year is listed, this topic was genuinely examined that year.

A topic that keeps reappearing is a topic JAMB keeps testing. Newer years matter most, because question style drifts.

Mathematics · Sequences and Series Sample 1 of 3

Instruction: Choose the correct option.\n\nFind the point of intersection of the lines \(x + 2y = 5\) and \(2x + y = 7\).

  • A (3, 1)
  • B (-2, 5)
  • C (6, -3)
  • D (4, 3)

Answer: A

From \(x + 2y = 5\), \(x = 5 - 2y\).\nSubstitute into \(2x + y = 7\): \(2(5 - 2y) + y = 7 \Rightarrow 10 - 4y + y = 7 \Rightarrow -3y = -3 \Rightarrow y = 1\).\nThen \(x = 5 - 2(1) = 3\). Intersection: \((3, 1)\).
