How do i write an explicit rule for this sequence?

= 10

Step-by-step explanation:

Note that consecutive terms have a common ratio, that is

50 ÷ 10 = 250 ÷ 50 = 1250 ÷ 250 = 5

This indicates that the sequence is geometric with n th term ( explicit rule )

= a

where a is the first term and r the common ratio,

Here a = 10 and r = 5, thus

= 10 ← explicit rule

you answer is a
