Given a sequence is defined by the explicit definition LaTeX: t_n=\:n^2+nt n = n 2 + n, find the 4th term of the sequence. (ie L
Reika [66]

Answer:

t_{4}=20

Step-by-step explanation:

Given:

The n^{th} term of the sequence is given as:

t_{n}=n^{2}+n

In order to find the fourth term of this sequence, we need to plug in 4 for n in the above expression and solve. This gives,

t_{4}=4^{2}+4\\t_{4}=16+4=20

Therefore, the fourth term of the sequence is t_{4}=20.

The product of some negative number and 3 less than twice that number is 209. find the number
zepelin [54]
The negative number would most likely be -19/2

let the negative number be x,
3 less than twice that negative number would be (2x-3)
hence,
equation form
x multiply by (2x-3) equals to 209
it would result in equation
2x^2-3x=209
2x^2-3x-209=0

hence using quadratic eqn
x=11 ( rej since qn stated x is a negative number)
x=-19/2
