1)

Find the 29th term of the arithmetic sequence in which a=13 and d = -2.5

- 57

Step-by-step explanation:

The n th term of an arithmetic sequence is

= a + (n - 1)d

where a is the first term and d the common difference

Here a = 13 and d = - 2.5, thus

= 13 + (28 × - 2.5) = 13 - 70 = - 57

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared

step-by-step explanation:

if e is the midpoint of bd, then bd is 14.
