There's a pattern here on alternate weeks - can you spot it? Wk2 = Wk1 + £3 Wk3 = Wk2 x 2 Wk4 = Wk3 + £3 Wk5 = Wk4 x 2 Wk6 = Wk5 + £3 Therefore using this pattern for the following weeks, we get: Wk7 = £58 Wk8 = £61 Wk9 = £122 Wk10 = £125 Wk11 = £250 Wk12 = £253 Wk13 = £506 Wk14 = £509 So therefore Wk14 - Wk 11 is: £509 - £250 = £259. Week 14 prize money is worth £259 more than week 11
