Question

What is the X in the sequence 4,196,16,144,36,100,64,X ?
a) 48
b) 64
c) 125
d) 256

Answer 1

Step-by-step explanation:

${2 }^{2} = 4 \\ {14}^{2} = 196 \\ 14 + 2 = 16 \\ {4}^{2} = 16 \\ {12}^{2} = 144 \\ 4 + 12 = 16 \\ {6}^{2} = 36 \\ {10}^{2} = 100 \\ 10 + 6 = 16 \\ {8}^{2} = 64 \\ {?}^{2} = ?$

then

14+2=16

4+12=16

6+10=16

8+? =16

?=16-8

?=8

?^2= 8^2

=64

Hope this is help for you
