Consider the following sequence 152, -76, 38, -19
Write a rule for the nth term and then find

a₇ =  2.375

Step-by-step explanation:

There is a common ratio r between consecutive terms, that is

r = = = = -

This indicates the sequence is geometric with nth term

= a₁

where a₁ is the first term and r the common ratio

Here a₁ = 152 and r = - , then

= 152 , so

a₇ = 152 = 152 × = 2.375

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
