The check for B2 is correct as it is, in B3 all you have to do it substitute 5 for x in your original equation.

For example
7x+2=12+5x
you got x=5
7(5)+2 = 12+5(5)
35+2 = 12+25
37 = 37 ✔

Describe the pattern 0.13, 0.65, 3.25, 16.25
Oksi-84 [34.3K]

Let n be the current term and n+1 be the next term

Then the pattern is: n+1 = n * 5

Step-by-step explanation:

Given series is:

0.13, 0.65, 3.25, 16.25

We can find the ratio between consecutive numbers to find the pattern

So,

Ratio = \frac{0.65}{0.13}\\=5

We can see that multiplying the previous term with 5 gives us the next term

0.13 * 5 = 0.65

0.65 * 5 = 3.25

3.25 * 5 = 16.25

Let n be the current term and n+1 be the next term

Then the pattern is: n+1 = n * 5
