Question

find the first four terms t1 = -54, tn = (tn-1)/3

Answer 1

Answer:

Terms of the series are -54, -18, -6, -2, -2/3, ........

Step-by-step explanation:

Given:

tn = (tn-1)/3

t1 = -54

Solution :

The next four terms will be find out by putting the value of previous term in the given expression for nth term.

Therefore,

t2 = (t1)/3 = -54/3= -18

t3 = (t2)/3 = -18/3 = -6

t4 = (t3)/3 = -6/3 = -2

t5 = (t4)/3 = -2/3

_______________________________

So, the terms of the given series are

-54, -18, -6, -2, -2/3, ........
