This slide focuses on finding the indicated terms of a sequence described by an algebraic formula.

2. In the NBA
Finals, the Toronto
Raptors scored the
first bucket of the
game via a Kawhi
dunk off an assist by
Lowry. If the dynamic
duo connects a
straight 87 shots
inside the paint, what
would be the final
score after the
buzzer?

3. The above situation will give us the following list:
2, 4, 6, 8, …
The numbers are listed in such a way that
every shot made will add 2 points to the
preceding score until the 87th shot is made.

4. Since sequences have patterns,
therefore they can be described by an
algebraic formula.
In a sequence, we designate the
number of terms as n and the first
term as a1, the second term as a2, and
so on up to the nth term or last term.

5. Find the first three terms in a
sequence described by the following:
1. an = - n + 5

6. 2.

7. 3. an = n2+ 5

8. Find the indicated terms of the
following sequence:
1. an = 2n + 1, a5

9. 2.

10. 3. an= (n+1)2 – 1,
a11

11. VALUES INTEGRATION
In life, you suffer sequence of
setbacks that shape you as a
person. During such times, do you
ask for advices or you like to face
it on your own? Why?

12. A. Write the first
three terms of the
sequence whose nth
terms is given by
the formula
1. an = n + 1
2. an = 3n + 1
3. an = 2(n + 3)
4. an =
5. an = 2n
B. Find the indicated
terms of the
following sequence:
1. an = 3n + 4, a12
2. an = (-1)n-1 n2, a11
3. an =
4. an = (n+1)2 - 1, a11
5. an = n(n-1), a11

13. A. Write the first three terms of the sequence whose nth
terms is given by the formula
1. an = - 6n
2. an = 3n
3. an = (n + 2) (n + 3)
B. Find the indicated terms of the following sequence:
1. an = - 3n2 + 2, a7
2. an = n + n + 1 + n + 2, a9
3. an = n (n + 1) (n + 2), a8
