Foundation November 2021 Paper 2 Q23
23 Here is a rule for a sequence.
| After the first two terms, each term is the sum of the previous two terms. |
The first five terms are \(\qquad p \qquad 23 \qquad q \qquad 57 \qquad r\)
Work out the values of \(p\), \(q\) and \(r\). [2 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(p = 11\) and \(q = 34\) and \(r = 91\) | B2 | B1 \(p = 11\) or \(q = 34\) or \(r = 91\) or \(q + 23 = 57\) oe equation in \(q\) |
Additional guidance
| For example, 34 written next to \(q\) in the sequence and not contradicted implies \(q = 34\) | B1 |
