3 A linear sequence starts \(\qquad 2 \qquad 5 \qquad 8 \qquad 11\)
Work out the position of the term that is the first to have a value greater than 500 [3 marks]
| Answer | Mark | Comments |
|---|---|---|
| \(3n\) seen | M1 | can be any letter eg \(3n + 2\) |
| \(3n - 1 \gt 500\) | M1dep | oe eg \(3n \gt 501\) |
| 168 | A1 | SC1 167 on answer line if no other marks scored |
Additional guidance
| 503 on answer line and 168 seen in working | M2A0 |
| Condone \(3n - 1 = 500\) or \(3n - 1 \geqslant 501\) or \(3n - 1 \geqslant 500\) | M2 |
| Condone \(3n \gt 500\) oe if recovered for correct answer | M2A1 |
| \(500 \div 3\) or \(501 \div 3\) would not imply M1 | |
| Listing terms with correct answer | M2A1 |
