Foundation November 2019 Paper 3 Q8
8 Here are the first five terms of a sequence.
1 3 6 10 15
Write down the next two terms of the sequence. (2)
| Answer | Mark | Mark scheme |
|---|---|---|
| 21, 28 | B2 | both correct |
| (B1 | one correct in the correct position or for \(15 + 6\ (= a)\) or \(a + 7\ (= b)\) where \(a \ne 21\) and \(b \ne 28\)) |
Additional guidance
May be written alongside the given sequence but if contradiction accept the answer line.
If both correct, accept in either order.
May be seen as “+6” next to the sequence
