List the next three terms in the following sequence<br>1,2,4,7, 11, 16​
Brrunno [24]

Answer:

22, 29, 37

Step-by-step explanation:

There is a pattern to find the next number in the sequence. The sequence is taking the previous number and adding the number it is in the sequence.

Notice how the first number being added is the number of the previous sum and the second number being added is always increasing by one

1+0=1

1+1=2

2+2=4

4+3=7

7+4=11

11+5=16

16+6=22

22+7=29

29+8=37

22, 29, 37

Answer: m<AOB is 60 degrees.

Step-by-step explanation: If BCD is 30 degrees, it intercepts the arc BA, and therefore, any angle that intercepts an arc is half of the arc it intercepts. Thus, AOB is 60 degrees.

X + 4 = 4x + 2

let’s put the x’s on one side and the numbers on the other
(whatever you do to one side, you have to do to the other)


x + 4 = 4x + 2
- 4 - 4x

x - 4x = 2 - 4
-3x = -2
—— ——
-3 -3

x = 2/3



to check this, we can put 2/3 in for x
(2/3) + 4 = 4(2/3) + 2
4 2/3 = 8/3 + 2
4 2/3 = 2 2/3 + 2
and there we can see both sides equal 4 and 2/3, making it true
