Given the following sequence, find the 50th term: 1.2, 1.4, 1.6, 1.8, 2, . . a. 9.8 b. 11 c. 10.8 d. 10.2

B.11

Step-by-step explanation:

The formula for an arithmetic sequence is

an = a1+d(n-1)

a1 =1.2   (it is the first term)

We can find the common difference by taking the second term and subtracting the first term

1.4-1.2 =.2

d=.2

n = the term number we are looking for

an = 1.2 + .2(n-1)

We are looking for the 50th term so n=50

a50 = 1.2 +.2(50-1)

      = 1.2 +.2(49)

      = 1.2+9.8

     =11

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32
