Answer:

(4 + 6 + x + 9 + 10 + 5)/6 = 7

34 + x = 42

x = 8

Answer: 8

Step-by-step explanation:

Mean = sum of terms ÷ no. of terms

first you do: 4+6+9+10+5 = 34

then see how much more you have to add onto 34 to get the lowest common multiple of 6 and 7.

(6 because there are 6 terms in total.)

You will get 42.

You then do 42-34 to get the term x which is 8.

To double check, try find the mean again:

4+6+8+9+10+5 = 42         42 ÷ 6 = 7

Not the best explanation but hope it helps:)
