Answer:
The Original Number is 36
Step-by-step explanation:
Given:
y is the number in units place
x is the number in tens place
Original Number = 
is equation 1
Now after interchanging the digits
New number = 
New Number = 27 + Original Number
Substituting Valus in above equation we get.

let this be equation 2
Adding equation 1 and 2 we get

Substituting value of y in equation 1 we get

x=3 and y=6
Original Number =
Answer:
8x²+5x+1
Step-by-step explanation:
3x²-5x+12
5x²+ x - 11
________
3x²+5x²= 8x²
}
5x+x =5x
}
12-11 =1
=
8x²+5x+1
the sequence is in multiples of 4 (2*4=8, 8*4=32, 32*4=128)
so 128*4=512, 512*4=2048, 2048*4=8192 & 8192*4=32768
2+8+32+128+512+2048+8192+32768=43690
