Notice that 6 = 4+2,

11=6+5

19 = 11+8

30 = 19+11

Following the same pattern,

(next number) = 30 + 14 = 44

44 is the next number in the sequence 4, 6, 11, 19, 30, ...

Use the ratio test to determine whether the series is convergent or divergent.

Kitty [74]

Answer:

Divergent

Step-by-step explanation:

Given series has general term as

$\frac{2^n}{n^2}$

n+1 th term = $\frac{2^(n+1)}{(n+1)^2}$

WE have to check whether this series converges or diverges

Let us use ratio test

Ratio of n+1 th term to nth term

= $\frac{2n^2}{(n+1)^2} =\frac{2}{(1+\frac{1}{n} }^2$

by dividing numerator and denominator by n square

Take limits as n tends to infinity

The ratio tends to 2

Since ratio >2, the series diverges

Y=4x-1 Y-2=x i need help substitution method

Anton [14]

Answer:

x = 1, y = 3

Step-by-step explanation:

x = y - 2, so y = 4 (y - 2) -1

solve normally now

y = 4 (y - 2) -1

y = 4y - 8 - 1 (distribute)

y = 4y - 9 (simplify)

+9 -y -y +9

9 = 3y

3 = y

y - 2 = x

(3) - 2 = x

x = 1
