Add the increasing numbers by one -
as in 0 1 2 3 4 5 6 etc
1 + 0 = 1
1 + 1 = 2
2 + 2 = 4
4 + 3 = 7
7 + 4 = 11
11 + 5 = 16
16 + 6 = 22

1/2 divide 3/4 Remember to rule for division of fractions. ; 'Change the sign to multiply and invert (turn over) the right hand fraction, then proceed as for multiplication of fractions'. Hence 1/2 X 4/3 = Cancel down by '2' 1/1 X 2/3 = 2/3 The answer!!!!
cube numbers next is 64 1 = 1 x 1 x 1 = 1³ 8 = 2 x 2 x 2 = 2³ 27 = 3 x 3 x 3 = 3³ then 64 = 4 x 4 x 4 = 4³
The factor that does not belong in the sequence is 1. The sequence follows a pattern of multiplying by 2: 2 x 2 = 4, 4 x 2 = 8, 8 x 2 = 16. However, 1 does not fit this pattern and disrupts the sequence.
Multiplication is the shortcut for showing a repeated addition: 1 x 36 = 1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1+1 +1+1+1+1+1 = 36 2 x 18 = 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 + 2 = 36 4 x 9 = 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 + 4 = 36 6 x 6 = 6 + 6 + 6 + 6 + 6 + 6 = 36
