Given the following sequence, find the 50th term: 1.3, 1.5, 1.7, 1.9, 2.1, . . a. 10.9 b. 11.1 c. 9.8 d. 8.9

B. 11.1

Step-by-step explanation:

The sequence is arithmetic, with a first term (a1) of 1.3 and a common difference (d) of 0.2.

The n-th term (an) is given by the equation ...

... an = a1 + (n -1)·d

So, the 50th term is ...

... a50 = 1.3 + (50-1)·0.2 = 1.3 +9.8 = 11.1

8+10

step-by-step explanation:

you multiply 4 by 2 and 5 by 2

step-by-step explanation:

f(gx)=f(1/x+2)

=(1/x+2)+2

=(1+2x)/2+2

=(1+2x+4)/2

= (2x+5)/2
