Generalize the pattern by finding the nth term.
Veseljchak [2.6K]

Answer:

4n+2

Step-by-step explanation:

The common difference between the terms is 4 which means that the sequence is an arithmetic sequence.

The general formula for arithmetic sequence is:

a_{n}=a_{0}+(n-1)d

where a_n is the nth term, a_0 is the first term and d is the common difference between them.

We know that

a_{0}=6\\d=4

Putting the value in general formula:

a_{n}=6+4(n-1)\\a_{n}=6+4n-4\\a_{n}=4n+6-4\\a_{n}=4n+2\\

So the generalized pattern is 4n+2 ..

in how many year will rs 8000 amount to rs 13824 at 20% per annum interest compounded annually? please please help me out​
icang [17]

Answer :-

<h3>3 years</h3>

step by step explanation:-

Let the time be x

principal = rs 8000

Amount = rs 13824

rate = 20% p.a

A = P(1+r/100)^n

13824 = 8000 ( 1 + 20/100)^n

=> 13824/8000 = (120/100)^n

=> 13824/8000 = (24/20)^n

=> (24/20)³ = (24/20)^n

=> 3 = n

=> n = 3 years
