Write the explicit formula for the arithmetic sequence 11, 14, 17, 20, . . . What is term number 54 in this sequence?
Natalka [10]

Answer:

15 or 16. 54 is not listed.

Step-by-step explanation:

pretend that 11 is 0. that means 54 is 43.

then you do 43 divided by 3 or 43/3  

but looks like the number 43 isn't divisible. it is 14.33333 repeating decimal.

Same if you really use your time and count. So i dont know if u meant 53 it will be 53 if you meant 56 it will be 16.

b

, where  

m

is the slope and  

b

is the y-intercept.

y

=

m

x

b

Find the values of  

m

and  

b

using the form  

y

=
