Answer 2

Answer:

The next term in the given series is 200

Step-by-step explanation:

As it is given the series includes the following numbers:

8, 32, 72, 128

If we subtract $t_{2} - t_{1}$ i.e. 32-8= 24

let us assume $x_{1}$=24

Now subtracting $t_{3} - t_{2}$ i.e. 72-32= 40

let us assume $x_{2}$=40

Now subtracting $t_{4} - t_{3}$ i.e. 128-72= 56

let us assume $x_{3}$=56

If we turn our attention towards $x_{1}$, $x_{2}$ and $x_{3}$

We can clearly see that the difference between all is 16.

So to find the next term,

$t_{5}$ = 128 + (56 + 16)

$t_{5}$ = 200
