what is your question tell me cleraly

Answer 2

Answer:

The next number is 273

Step-by-step explanation:

The given series is : 1, 10, 44, 135, 272, .....

Here , 10 is obtained by adding 1 to previous number and then multiplying the sum by 5 : (1 + 1) × 5 = 2 × 5 = 10

44 is obtained by adding 1 to previous number and then multiplying sum by 4 : (10 + 1) × 4 = 44

Continuing likewise :

( 1 + 1 ) × 5 = 10

( 10 + 1 ) × 4 = 44

( 44 + 1 ) × 3 = 135

( 135 + 1 ) × 2 = 272

( 272 + 1 ) × 1 = 273

Therefore, the required number in the given series is 273.
