Find a formula for the general term an of the sequence, assuming that the pattern of the first few terms continues. {5,5/3,5/9,5
Tanya [424]

The formula for the general term of the given sequence 5, 5/3, 5/9, 5/27 is  a_{n} = \frac{5}{3^{n} }.

According to the given question.

We have a sequence  5, 5/3, 5/9, 5/27.

As, we know that "a sequence is an arrangement of any objects or a set of numbers in a particular order followed by some rule"

If we see the given sequence 5, 5/3, 5/9, 5/27 it is following a pattern in which the nummerator of all the terms are same but the denominator is increasing by by power to 3 like 3^0 = 1, 3^1 = 3, 3^2 = 9 and so on.

Thereofre, the genereal term  a_{n}, of the given sequence is given by

a_{n} = \frac{5}{x^{n} } , where n belong to whole numbers.

Hence, the formula for the general term of the given sequence 5, 5/3, 5/9, 5/27 is  a_{n} = \frac{5}{3^{n} }.

The ratio of the lengths of the sides of a triangle ABC is 3:4:6. M, N, and K are the midpoints of the sides. Perimeter of the △
juin [17]

Given that in a trianlgle the sides AB, BC, CA are in the ratio 3:4:6.

Let AB = 3k, BC = 4k and CA = 6k.

Then perimeter =3k+4k+6k = 13k

M, N, K are mid points of the sides.

By mid point theorem MN = 3k/2, NK = 4k/2 and KM = 6k/2

Hence perimeter of MNK = 13k/2 =5.2 (given)

Solve for k

k=2(5.2)/13 = 0.8

Hence sides are

AB = 3k = 3(0.8) = 2.4 in

BC = 4k= 3.2 in

CA = 4.8 in
