(a) Simplify \(\quad c + c + c + c + c\) (1)
(b) Simplify \(\quad 7w + 10y - 9w + 2y\) (2)
The \(n\)th term of a sequence is given by \(7n - 4\)
(c) Find the 1st term and the 5th term of the sequence. (2)

| \(7x + 35\) | M1 |
| \(7x + 3x = 8 - 35\) oe eg \(10x = 8 - 35\) or \(10x = -27\) or \(7x + 3x = -27\) | M1 |
| Working required Answer: –2.7 | A1 |
| (3) | |
| (8 marks) |
Notes
M1: a correct expansion of the bracket (need not be in an equation)
M1: for isolating terms in \(x\) and number terms
ft from an incorrect expansion in the form \(7x + c\) or \(x + 35\)
A1: (dep on M1) oe
