146, 74, 38, 20, ? what would the next number be in this sequence?

1 answer:

3 0

Looking at the numbers, we can see that the differences are 72, 36, and 18. Notice that they are each factors of the next by the same constant 2.

18 * 2 = 36
36 * 2 = 72

There, it means that 18/2 will be subtracted from 20.

20 - 18/2
= 20 - 9
= 11

The next number in the sequence would be 11. Hope this helps!

Answer: $\boxed{\bold{3\sqrt{2}x-36x}}$

<><><><><><><>

Explanation: $\downarrow\downarrow\downarrow$

<><><><><><><>

[ Step One ] Remove Parenthesis (a) = a

$\bold{7\cdot \:3\sqrt{2}x-3\cdot \:3\sqrt{16}x-3\cdot \:3\sqrt{8}x}$

[ Step Two ] Simplify Equations

$\bold{7\cdot \:3\sqrt{2}x: \ 21\sqrt{2}x}$

$\bold{3\cdot \:3\sqrt{16}x: \ 36x}$

$\bold{3\cdot \:3\sqrt{8}x: \ 18\sqrt{2}x}$

[ Step Three ] Rewrite Equation

$\bold{21\sqrt{2}x-36x-18\sqrt{2}x}$

[ Step Four ] Add Similar Elements

$\bold{21\sqrt{2}x-18\sqrt{2}x=3\sqrt{2}x}$

[ Step Five ] Rewrite Equation

$\bold{3\sqrt{2}x-36x}$

Completely simplify the expression 4x+10+6x+2x4x+10+6x+2x

oksian1 [2.3K]

Simplifying 4x + 20 = 6x + -10 Reorder the terms: 20 + 4x = 6x + -10 Reorder the terms: 20 + 4x = -10 + 6x Solving 20 + 4x = -10 + 6x Move all terms containing x to the left, all other terms to the right. Add '-6x' to each side of the equation. 20 + 4x + -6x = -10 + 6x + -6x Combine like terms: 4x + -6x = -2x 20 + -2x = -10 + 6x + -6x Combine like terms: 6x + -6x = 0 20 + -2x = -10 + 0 20 + -2x = -10 Add '-20' to each side of the equation. 20 + -20 + -2x = -10 + -20 Combine like terms: 20 + -20 = 0 0 + -2x = -10 + -20 -2x = -10 + -20 Combine like terms: -10 + -20 = -30 -2x = -30 Divide each side by '-2'. x = 15 Simplifying x = 15
