vitfil [10]

Answer:

(A)

C_n=3+2n

(B)

C_1_0=23

Step-by-step explanation:

(A)

we are given

C_n_+_1=C_n+2

C_1=5

Firstly, we will find few terms

C_2=C_1+2

C_2=5+2

C_2=7

C_3=C_2+2

C_3=7+2

C_3=9

C_4=C_3+2

C_4=9+2

C_4=11

so, we will get terms as

5, 7 , 9 , 11

we can see that this is arithematic sequence

First term =5

common difference =d=7-5=2

now, we can use nth term formula

C_n=C_1+(n-1)d

now, we can plug values

C_n=5+2(n-1)

C_n=5+2n-2

C_n=3+2n

(B)

we can plug n=10

C_1_0=3+2\times 10

C_1_0=23
