If 15 + x,28 – x, and 29 + x form an arithmetic sequence what is the value of x?

3.

Step-by-step explanation:

If its an AS it well have a common difference, so 3rd term - 2nd term should = 2nd term - first term:-

29 + x - (28 - x) =  28 - x - (15 + x)

2x + 1 = 13 - 2x

4x = 12

x = 3.

The sequence is

15 + 3, 28-3, 29 + 3

= 18, 25, 32

which is arithmetic with common difference 7.

i think it's either c or d

step-by-step explanation: the entire question is extremely odd. 04 obviously refers to the interest rate. honestly i will say the answer is c. because the (2 x 12) part would mean it's compounded semiannually. i'll say choose c.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
