Answer:

<em>4 is the unit's digit of the 20th number.</em>

Step-by-step explanation:

Let us try to find out a pattern for the unit's digit of the terms.

1st term is 1, so unit's digit of 1st term is 1.

2nd term $1^{2} + 3 = 4$ so unit's digit is 4.

3rd term $4^{2} + 3 = 19$ so unit's digit is 9.

4th term $19^{2} + 3 = 364$ so unit's digit is 4.

5th term's unit digit: Square of unit's digit of 4th term + 3

$4^{2} + 3 = 19$ i.e. 9.

We can see that the pattern is

3rd, 5th, 7th ...... terms have 9 as the unit's digit.

2nd, 4th, 6th.... terms have 4 as the unit's digit.

So, 20th term will have 4 as the unit's digit.

Sopve each quadratic equation 1) 3x^2+6x+6=0

NeX [460]

Hello from MrBillDoesMath!

Answer: There is no real solution to equation 1)

(It's implied that other equations are involved in this problem The other equations were not provided by the author)

Discussion:

Divide each side of the equation by 3. This gives

x^2 + 2x + 2 = 0

(x^2 + 2x + 1) + 1 = 0

(x+1)^2 +1 = 0

(x+1)^2 = -1

But any number squared is positive so the last equation has NO solution

Thank you,

MrB

2/8 * 7

2/8 will simplify

Divide the top and bottom by 2

12/8 = 1/4

1/4*7

7/4

We need to change this from an improper fraction to a mixed number

4 goes into 7 once with 3 left over
