1x1 4x4 7x7 10x10
add 3 to previous number then square it.
49
You could put 49 in between the 16 and the 100.
16. 1 is added to the difference each time: 1 + 1 = 2 2 + 2 = 4 4 + 3 = 7 7 + 4 = 11 11 + 5 = 16 [the missing number] 16 + 6 = 22
16 out of 112 = 16/112 x 100 % = 1/7 x 100 % ~= 14.29%
1 century = 100 years 16 centuries = 16 x 100 = 1600 years.
49
You could put 49 in between the 16 and the 100.
The missing number is 100 because 1 meter = 100 centimeters.
49 The sequence is the squares of numbers that increase by 3 each time: 1² = 1 (1 + 3 )² = 4² = 16 (4 + 3)² = 7² = 49 (7 + 3)² = 10² = 100 (10 + 3)² = 13² = 169

1/10 + 6/100 = 10/100 + 6/100 = 16/100.
1/16 as a percentage = 100*1/16 = 6.25%

1 is 6.25% of 16 (divide 1 by 16 and then multiply the answer by 100).
