Position               (n) TermRule ->5 X Table

1    2    3    4    53    8   13  18   23           (Rule: +5) +5  +5  +5  +55  10   15   20   25

Term to Position Rule =5 n  - 2

(Position x 5) - 2 = Term to position rule.

e.g. 100th term =5 x 100 = 500500 - 2 = 498

Prime - A number that is only ÷ by 1 & Itself.1 is NOT a prime NumberFirst prime number is 2 - only even prime number2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97

Square -Made by multiplying numbers by themselves.1x1=12x2=43x3=94x4=165x5=256x6=367x7=498x8=649x9=8110x10=100

Cubed -Multiply 3 of number togethere.g.  a x a x a = __1, 8, 27, 64

Square root - Opposite of squaring

Cube root -Opposite of cubing

Don't include 1 = 1x - Wrong                         x - Correct

3x + 2x = 5x7x - 6x = x3xy + 2xy = 5xy  ↑       ↑      ▲   Same     9xy³ + 3xy³ = 12xy³3x + 2y + 4x + 6y = 7x + 8y2x - 3y + 7x - 2y = 9x - 5y
