Amrita thinks of a number. She doubles it, adds 9 , divides her answer by 3 and finally subtracts 1 . She obtains the same numbe

maks197457 [2]

Answer:

Amrita's number is 6

Step-by-step explanation:

x Double the unknown number

2x Add 9

2x + 9 Divide the answer by 3

2/3x + 3 Subtract 1

2/3x + 2 Set this equal to the original number

2/3x + 2 = x

-2/3x -2/3x Subtract 2/3x from both sides

2 = 1/3x Multiply both sides by 3

6 = x

3,5,8,12....... state the rule in the sequence

2n + 1

the number before n is the difference (what it goes up in), and the second is the ‘zeroth’ term: you take away the 2 you got from the first value, 3, and get 1 :)
