Answer 1

Answer:

T10=65

t10=a+9d

t15=80

t15 =a+14d

T15-t10= 80-65=15

a+14d--a--9d =5d

5d=15

d=15/5=3

1t10= a+9×3 =65

a= 65-27= 38

200 =tn

200=38 +(n--1 )×3

(n-1)= (200-38)/3 =54

n=54+1=55

T55 of the sequence is 200 is the term of the sequence

Verification

t55 =38+54×3=200

Answer 2

Answer:

1) No you won't be able to see your reflection because it's completely dark(Unless you have night vision specs)

2) Not sure..

3) There should be an opaque material.

There should be a source of light and screen.

The object must be placed in the path of light. Then shadow is formed on the screen.

Hope this helps Army
