Evaluate the expression 2a^3 +-d when
a = 5, b= 14. c= 7, and d 10.

240.

Step-by-step explanation:

Simply plug the given values into the equation, as follows, then run it through your calculator:

Since the values B and C don't exist in this context, we can ignore them.

Running that equation through our calculator, we get 240.

(If you don't have a calculator, it's important to remember PEMDAS while you're solving this equation)

, and

for

step-by-step explanation:

we can analyze the pattern at which the terms increase. let us denote , , , so that we can call

note the following:

the pattern: to get the next term value, we just add the next term number (e.g. 1st, 2nd, to the previous term value (term values are the given numbers in the question, 1, 3, 6, 10, 15,

from , to get to , we add

from , to get to , we add

etc.

we need to form a recursive formula, a formula that has the next term as a function of the previous term. so a possible recursive formula can be

, and for

answer:   y=2x-3
