Are the first three terms of a linear number sequence. 3.1

If the value of is four, write down the first three terms.

3.2

Determine the formula of , the general term of the sequence

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

he has now walked a total of what?

if i know what this is maybe i can

step-by-step explanation:

ratio is 2 : 9

the answer is three

13.5 : 3
