Answer 2

Answer:

The next number in the series 7,32,81,160 is 275.

Step-by-step explanation:

• For the series type of problems, we should always check with addition, subtractions, common difference, multiplication.
• For the current problem, the numbers have multiplication, addition, and common difference of increasing odd numbers.

7 = 6 * 1 + 1

32 = 7 * 4 + 4

81 = 8 * 9 + 9

160 = 9 * 16 + 16

Here,

1. The first number starts with 6 and it is incremented by 1 in each number.
2. The second number starts with 1 and it is incremented by increasing odd numbers starting with 3, 5, 7.
3. The third number is the same as the second number.

Next number can be written by following the above 3 steps as:

First number should be incremented by 1 from previous number's first number which is 9.

So the first number is 10.

Next, the second number is obtained by adding an odd number to the previous number's second number which is 16. Since the last odd number was 7, add 9 to 16.

So the second number is 25

Since the third number is same as second number.

So the third number is 25.

Hence the next number of the series is 10 * 25 + 25 = 275.
