There is a mistake in the way this mathproblem was solved.*54x 23'162+1,0801,232Your answer
konstantin123 [22]

We have to multiply 54 * 23, and check where the mistake is.

We start by multiplying 54 by 3, and it gives us 162

Then, we multiply 54 by 20, and it gives us 1080.

Then, we have to add these two results:

The mistake is where 6 is added to 8. It does not give 13, but 14.

The 1 of the 10 goes adding above the 1 in 162.

The result is 1,242.

What is the recursive rule for the sequence 1, −6, 36, −216, ... ? an=6⋅an−1 , a1=1 an=−6⋅an−1 , a1=1 an=−16⋅an−1 , a1=1 an=16⋅a
labwork [276]

Answer:

Option 2) a_n = -6(a_{n-1})            

Step-by-step explanation:

We are given the following sequence in the question:

1, -6, 36, -216, ...

We have to find the recursive relation for the sequence.

a_1 =1\\a_2 = -6 = -6(1) = -6(a_1)\\a_3 = 36 = -6(-6) = -6(a_2)\\a_4 = -216 = -6(36) = -6(a_3)

Thus, continuing in the following manner, we get,

a_n = -6(a_{n-1})

Thus, the recursive rule is given by

Option 2) a_n = -6(a_{n-1})
