Answer:
10
Step-by-step explanation:
Since F is the midpoint of EG, EF and FG are equal. We know that FG is 4 units, so EF must be 4 units. We also know that FH and EF make EH, so we substitute the values that we have.
FH + EF = EH
6 + 4 = EH
EH = 10
Answer:
See below.
Step-by-step explanation:
Formula:

First term: n = 1

Second term: n = 2

Third term: n = 3

Fourth term: n = 4

Tenth term: n = 10

N is the same as 17, so it equals 17.
