Question
Describe the pattern in the numbers. Write the next number in the pattern.
3, 1, 1/3 , 1/9 , …
Hint:
A sequence of numbers which has a common difference between any two consecutive numbers is called an arithmetic progression (A.P.). The arithmetic progression general form is given by a, a + d, a + 2d, a + 3d, . . .. Hence, the formula to find the nth term is:
an = a + (n – 1) × d
The correct answer is: 3, 1, 1/3 , 1/9 , 1/27
We have given a pattern
3, 1, 1/3 , 1/9 , …
We have to find the next term of pattern
If we analyse the pattern we found that each term is obtained by multiplying previous term by 1/3.
3 x 1/3 = 1
1 x 1/3 = 1/3
1/3 x 1/3 = 1/9
Then , the next term will be
1/9 x 1/3 = 1/27
So the pattern will be
3, 1, 1/3 , 1/9 , 1/27
We have to find the next term of pattern
If we analyse the pattern we found that each term is obtained by multiplying previous term by 1/3.
Then , the next term will be
So the pattern will be
