Inserting two geometric means between the numbers would make a geometric sequence with first term equal to 7 and fourth term equal to 875. To find the common ratio, use the equation, an = a1 x r^(n - 1) Substituting the values, 875 = (7) x r ^(4 - 1) The value of r is 5. Thus, the two geometric means are 35 and 175.
