Question 1: 50^2 + 2= 2502 Question 2: a, b , a+b, a+2b, 2a+3b, 3a+5b, 5a+8b plus the 2 behind to get the one in font: 5a+8b Question 3: 0.87(30) is 2017 0.87(ans) is 2018 then go on: 20 grams Question 4: W= n+2 Question 5: 4n-1 Question 6: 3n-7 Question 7: 4n+5 Question 8: 1st sequence: 6 terms 2nd sequence: 3 terms 6+3= 9 maybe Question 9: 4n-1= 319 = 4n=320 N= 80 so yes Adeel is correct Question 10: 53-6n= -100 6n= 153 but they are not divisible by each other so yes -100 is not in the sequence. Question 11: 2, 17,32
