Let the first term be <em>a</em>

Given, a = -5

d = 10

So, we need to find next three terms i.e. second, third and fourth terms.

Using \: formula \:  =  >   a_{n} = a + (n - 1)d

a _{2} =  - 5 + (2 - 1)10 \\  =  - 5 + 10 = 5 \\ a _{3} =  - 5 + (3 - 1)10 \\  =  - 5 + 20 = 15 \\ a _{4} =  - 5 + (4- 1)10 \\  =  - 5 + 30= 25

How do i prove 2sec^2x-2sec^2xsin^2-sin^2x-cos^2x=1
kramer
2\sec^2x-2\sec^2x\sin^2x-\sin^2x-\cos^2x=2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)

Since \sin^2x+\cos^2x=1, you have

2\sec^2x(1-\sin^2x)-(\sin^2x+\cos^2x)=2\sec^2x\cos^2x-1

and since \sec x=\dfrac1{\cos x}, you end up with 2-1=1.

What is the coefficient of xy^2<br> in the expansion of (x+y)^3?
Basile [38]

Step-by-step explanation:

Using Binomial Expansion,

(x + y)³

= 3C0 * x³ + 3C1 * x²y + 3C2 * xy² + 3C3 * y³.

Therefore the coefficient of xy² is 3C2 = 3.
