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
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!!!!
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
The factors of 4 are 1, 4, and 2.
1/4 or 1/2 1/2 = 2/4 so 1/2 is larger than 1/4 1/2 > 1/4 ========
i0 = 4; in = in-1 - 3
Double the previous number
t(n) = 3(n-1) + 1, for n = 1, 2, 3, etc
The rule is multiply the previous term by -1 to find the next term.
The pattern will be +2, +3, +4, +4
add 4 to every other number 1(+4)=5, 5(+4)=9 2(+4)=6
+2, +3, +2
3 is the answer
2 squared 1 = 4 so the divisibility rule is that it is divisible by 1, 2 and 4.
3 4 6 9 13 18...1....2....3....4......5
5-30-6-42-7-56-8-72
4*2-2=6 6*2-2=10
