Question

Read the numbers and decide what the next number should be. 256 196 144 100 64 36 16

Answer 1

Answer:

The next number is $4$

Step-by-step explanation:

we have

$256, 196, 144, 100, 64, 36, 16,...x$

we know that

$256-196=60$

$196-144=52=60-8$

$144-100=44=52-8$

$100-64=36=44-8$

$64-36=28=36-8$

$36-16=20=28-8$

therefore

The next number is equal to

$16-x=20-8$ ------> solve for x

$16-x=12$

$x=16-12=4$

Answer 2

340? TBD add the two numbers.
