1 Expert Answer

Given the sequence

ii 7 26 101 400

Information technology looks like the relationship betwixt successive number is

xn+1=4xdue north-n

Where northward = ane, ii, 3, 4...

and xn = two, 7, 26, 101 400

Permit's cheque this.

The first number is ii

xtwo = 4(2)-1 = 7

The 2nd number is vii

103 = 4(7) -2 = 26

The 3rd number is 26

x4 = 4(26) - 3 = 101

The quaternary number is 101

tenfive = 4(101) - 4 = 400

The fifth number is 400

xvi = 4(400) - five = 1595

The 6th number should be 1595

Well, it looks like the formula should be:

   A1 = two

   Anorthward = 4*Adue north-i - (n-1)

Cheque information technology out !
