Answer: b = 8

Step-by-step explanation: To solve for <em>b</em> in this equation, we want to get <em>b</em> by itself on the left side of the equation.

Since 19 is being subtracted from <em>b</em>, to get <em>b</em> by itself,

we need to add 19 to the left side of the equation.

If we add 19 to the left side, we must also add 19 to the

right side in order to keep our equation balanced.

Notice that on the left side, -19 and +19 cancel

each other out so we're simply left with <em>b</em>.

On the right side, -11 + 19 equals 8.

So we have <em>b = 8</em>.

Trava [24]

Answer:

0.527

Step-by-step explanation:

From the question,

The sequence is Geometry Progression (G.P)

Tₙ = arⁿ⁻¹.......................... Equation 1

Where n = number of term, a = first term, r = common ratio

Given: n = 7, a = 6, r = 2/3

Substitute these values into equation 1

T₇ = 6(2/3)⁷⁻¹

T₇ = 6(2/3)⁶

T₇ = 6(64/729)

T₇ = 384/729

T₇ = 0.527

Hence, the 7th term of the sequence is 0.527
