Answer:

f(n)=f(n-1)+22.

Step-by-step explanation:

Note: In the given function it should be (n-1) instead of (n=1).

Consider the given function is

f(n)=-11+22(n-1)

It is the explicit form of an A.P.

For n=1,

f(1)=-11+22(1-1)=-11+0=-11

For n=2,

f(2)=-11+22(2-1)=-11+22=11

Common difference is  

d=a_2-a_1=11-(-11)=11+11=22

The recursive formula of an A.P. is

f(n)=f(n-1)+d

Substitute d=22 in the above formula.

f(n)=f(n-1)+(22)

f(n)=f(n-1)+22

Therefore, required recursive formula is f(n)=f(n-1)+22.

How do you solve -10+2y=7
Eva8 [605]

Answer

y = \frac{17}{2}

Step-by-step explanation:

-10 + 2y = 7

Add 10 to both sides of the equation

2y = 7 + 10

Add 7 and 10

2y = 17

divide each term in 2y=17 by 2

\frac{2y }{2} = \frac{17}{2}

Divide y by 7

y = \frac{17}{2}
