Answer 1

We have a relationship equation given for finding numbers in this sequence.

Also first term a_{​​​​​​1} is given as -4.

Using provided info ,

We get a_{​​​​​​1=} -4

a_{​​​​​​2 =} 32

a_{​​​​​​3 =} 2048

a_{​​​​​​4 =} 8388608

Solution a = - 4 anti = zan a = 4 (given) Az can be written as (from 0 ) at 2a² Az = 2(-4) 2 Az = 2 X 36 = 32 a3 can Written as 2 2a2 92 + 1 = a3= 2( 32) 2 a 3 = 2x1024 = 2048 a 4 can be Written as, 2 a3+1 = 2a 2 (2048)2 aa ад - 2 x 4194 304 = 8388608
