The terms of this sequence increase by the same amount each time _,_,17_,_,29

9, 13, 17, 21, 25, 29

Step-by-step explanation:

Since there is an equal increase of the same amount, the sequence is arithmetic with n th term

Substituting a = 9 and d = 4 into the n th term expression

= 9 + 4(n - 1) = 9 + 4n - 4 = 4n + 5

= a + (n - 1)d

where a is the first term and d the common difference

The third term and sixth term are therefore

a + 2d = 17 → (1)

a + 5d = 29 → (2)

Subtract (1) from (2) term by term, eliminating a, that is

3d = 12 ( divide both sides by 3 )

d = 4

Substitute d = 4 into either of the 2 equations and solve for a

Substituting into (1)

a + 2(4) = 17

a + 8 = 17 ( subtract 8 from both sides )

a = 9

Thus the first term is 9 and the common difference d = 4

The sequence of terms is therefore

9, 13, 17, 21, 25, 29

Substituting a = 9 and d = 4 into the n th term expression

= 9 + 4(n - 1) = 9 + 4n - 4 = 4n + 5

=====================================

explanation

the graph has a slope of 1/3 because each time you move up 1, you go to the right 3. so, slope = rise/run = 1/3. we can cross choice a off the list since we want a slope of 3, rather than 1/3.

the first table shown has a slope of -3. this is because the rise is -6 and the run is 2, so slope = rise/run = -6/2 = -3. note how x increases by 2 each time (run) and y drops by 6 each time (rise). choice b can be eliminated.

the second table has a slope of 3. each time x goes up by 1, the y values increase by 3. slope = rise/run = 3/1 = 3. alternatively you can use the slope formula to prove that the slope is 3 here. use any two rows of values to generate the two points. choice c is one of the answers

the third table also has a slope of 3. let's use the slope formula to prove as such. i'm going to use the first two rows of the table. so i'll use the two points (2,1) and (5,10)

m = slope

m = (y2-y1)/(x2-x1)

m = (10-1)/(5-2)

m = 9/3

m = 3 so we get a slope of 3

choice d is the other answer

think about it deeply and passionately about this property

i am sorry
