Question

What is the rule of this pattern
6,30,150,750

Answer 1

a_1 = 6

a_n = 5 × a_n-1

Explanation:

30/6 = 5

150/30 = 5

750/150 = 5

The rule is to start with 6 and multiply each number by 5 to get the next number.

a_1 = 6

a_n = 5 × a_n-1

Answer 2

Explanation:

To get the next term, you multiply the previous term by 5

tn = 5*t_(n -1)

a1 = 6

a2 = a1 * 5

a2 = 6 * 5

a2 = 30

a3 = 5*a2

a3 = 5 * 30

a3 = 150

and so one
