Question

1,10,44,135,272,? what should be the next number

Answer 1

The next number will be 273

Explanation

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

Here 10 is obtained by adding 1 with 1, and then multiplied by 5, like $(1+1)*5= 2*5=10$

Now 44 is obtained by adding 1 with 10 and then multiplied by 4, like $(10+1)*4= 11*4=44$

Like this way.......

$(1+1)*5=2*5=10\\ \\ (10+1)*4=11*4=44\\ \\ (44+1)*3= 45*3=135\\ \\ (135+1)*2=136*2=272\\ \\ and\\ \\ (272+1)*1=273*1=273$

So, the next number in the series will be 273.
