First we have to figure out what the next 2 terms are, ya reckon ?

Look at the terms we have:

From the 1st to the 2nd term . . . add <em>2</em>
From the 2nd to the 3rd term. . . add <em>4</em>
From the 3rd to the 4th term . . . add <em>6</em>
From the 4th to the 5th term . . . add <em>8</em>

So there's the pattern we want.

To get the next term,          we add  <em>10</em>  to 17, and get  27.
And for the one after that, we add  <em>12</em>  to 27, and get 39 .

To answer the question, the sum of (27 + 39) is<em>  <u>66</u></em> .

4. A random variable X has a mean of 10 and a standard deviation of 3. If 2 is added to each value of X, what will the new mean
Ede4ka [16]

Adding 2 to each value of the random variable X makes a new random variable X+2. Its mean would be

E[X+2]=E[X]+E[2]=E[X]+2

since expectation is linear, and the expected value of a constant is that constant. E[X] is the mean of X, so the new mean would be

E[X+2]=10+2=12

The variance of a random variable X is

V[X]=E[X^2]-E[X]^2

so the variance of X+2 would be

V[X+2]=E[(X+2)^2]-E[X+2]^2

We already know E[X+2]=12, so simplifying above, we get

V[X+2]=E[X^2+4X+4]-12^2

V[X+2]=E[X^2]+4E[X]+4-12^2

V[X+2]=(V[X]+E[X]^2)+4E[X]-140

Standard deviation is the square root of variance, so V[X]=3^2=9.

\implies V[X+2]=(9+10^2)+4(10)-140=9

so the standard deviation remains unchanged at 3.

NB: More generally, the variance of aX+b for a,b\in\mathbb R is

V[aX+b]=a^2V[X]+b^2V[1]

but the variance of a constant is 0. In this case, a=1, so we're left with V[X+2]=V[X], as expected.
