1.(4/9)^2=(4/9)(4/9)=16/81
2. Make all denominators the same so 1/3=6/18 2/9=4/18 and finally, 1/2=9/18
3. Add the three fractions together to get 19/19 which is just 1 however for this question we shall leave it as 19/19
4. Remember KFC so our question becomes 16/81 x 19/19
5. Work this out as 16/81

What is the sum of the first 100 terms of the sequence 4,9,14,19, ...?
Nadya [2.5K]

Answer:

25150

Step-by-step explanation:

First, we have to see that this is an arithmetic sequence... since to get the next element we add 5 to it.  (a geometric sequence would be a multiplication, not an addition)

So, we have a, the first term (a = 4), and we have the difference between each term (d = 5), and we want to find the SUM of the first 100 terms.

To do this without spending hours writing them down, we can use this formula:

S = \frac{n}{2} * (2a + (n - 1) * d)

If we plug in our values, we have:

S = \frac{100}{2} * (2 * 4 + (100 - 1) * 5) = 50 * (8 + 99 * 5)

S = 50 * (8 + 495) = 50 * 503 = 25150
