    The general relationship between each pair in terms of decimal values, powers of 2 and number of bit required are shown in form of table below:

    Binary No. Decimal Value Power of 2 No. of Bits (n) Relation Ship

    a=00011111 31 2⁵-1 n=5 b=a+1

    b=00100000 32 2⁵ n+1=6

    a=00111111 63 2⁶-1 n=6 b=a+1

    b=01000000 64 2⁶ n=6+1

    a=01111111 127 2⁷-1 n=7 b=a+1

    b=10000000 128 2⁷ n+1=8
