What is the sum of the first 10 terms of the geometric sequence 4, -12, 36, -144
Oksanka [162]

The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058

The given geometric sequence is:

4, -12, 36, -144

The first term, a = 4

The common ratio,

r = \frac{-12}{4}\\r = -3

Since we are looking for the sum of the first 10 terms

The number of terms, n = 10

The sum of the first n terms of a geometric sequence is given as:

S_n = \frac{a(1-r^n)}{1-r} \\S_n = \frac{4(1-(-3)^{10}}{1-(-3)} \\S_n = \frac{4(1-59049)}{4} \\S_n = -59048

The sum of the first 10 terms of the sequence 4, -12, 36, -144 is -59058

Which pair of measurements is not equivalent?
KonstantinChe [14]
If you would like to know which pair of measurements is not equivalent, you can calculate this using the following steps:

1 yard = 3 feet
1 foot = 12 inches
1 mile = 5280 feet

8 yards = 8 * 3 feet = 24 feet
2 feet = 2 * 12 inches = 24 inches
10 feet = 10 * 12 inches = 120 inches
3 miles = 3 * 5280 feet = 15,840 feet

Not equivalent: <span>3 miles, 15,480 feet.</span>
