2,3,6,13,28?

• answer is 59
  sequence is 2*2-1=3
  3*2-0=6
  6*2+1=13
  13*2+2=28
  28*2+3=59

• 2 3 6 13 28 59
  1 3 7 15 31 (difference)
  *2+1 *2+1 *2+1 *2+1
  2+1=3
  3+(1*2+1=3)=6
  6+(3*2+1=7)=13
  13+(7*2+1=15)=28
  28+(15*2+1=31)=59

• The answer is 59.
  2 4 8 16
  1 3 7 15 31
  2 3 6 13 28 59
  
  1. Find difference
  2. repeat again
  3. Sequence found multiple of 2 and add with below no. and repeat this again.

• This series is 2^n-(n-1) , where n=1,2,3,.....
  Therefore answer will be n=6, 2^6-(6-1)=59

• (2^n)-m pattern where n=1,2,3,4,5 so on and m=0,1,2,3,4,5,6...so on.
  so ans will be (2^6)-5=64-5=59 :)

• answer is 59
  because
  3*2=6+(0)=6 then 6*2=12+(1)=13 then 13*2=26+(2)=28 then 28*2=56+(3)=59
  so ans=59(2,3,6,13,28,59)
