7+4=11 11+8=19 19+16=35 35+32=67 so the next no. is 67..............
Assuming the area is 35 SQUARE metres and not 35 metres, Area = Base*Altitude/2 So 35 = Base*14/2 = 7*Base Base = 5 metres.
11 comes next.
Divide the number starting from the smallest prime number, which is 2. 140 / 2 = 70 70 / 2 = 35 140 can be divided by 2 twice only Next we repeat with the next prime number, which is 3. 35 is not divisible by 3 so we move on to the next prime number, which is 5 35 / 5 = 7 35 can be divided by 5 once only Next prime number is 7 7 / 7 = 1 [Your objective is to get a 1] Working could be: 140 / 2 = 70 70 / 2 = 35 35 / 5 = 7 7 / 7 = 1 Prime factorization of 140 = 2 x 2 x 5 x 7 or 2^2 x 5 x 7

66 and 4/4's.
59, by adding successive numbers starting with seven:35+7=42, 42+8=50, 50+9=59.
7+4=11 11+8=19 19+16=35 35+32=67 so the next no. is 67..............
Assuming the area is 35 SQUARE metres and not 35 metres, Area = Base*Altitude/2 So 35 = Base*14/2 = 7*Base Base = 5 metres.
The number 7 comes next.
70

11 comes next.
59 is the next number in this series.
7 then 7 then 5 then 6
