Answer 1

Explanation:

the answer is 8/5 i just did it on my quiz and got it right.

Answer 2

The given sequence is 25, 10, 4.

Notice that this is a geometric sequence because here we have equal common ratio.

So, common ratio : r =
`(a_(2))/(a_(1))`

=
`(10)/(25)`

= 0.4

So, each term is 0.4 times of it's previous term.

Hence, to get the next term of this sequence, multiply 0.4 with the third term 4.

So, fourth / next term = 4* 0.4 =1.6

Hence, next term of this sequence is 1.6.

Hope this helps you!
