A student saves money for school supplies. On the first day, the student saves ₱20, and each day after that the student saves ₱5 more than the previous day.

How much money will the student have saved in total after 10 days?

Answer: ₱425

Explanation & Solution:

Use the sum of an arithmetic series: Sn = n/2 (2a1 + (n - 1)d)

Where:

n = 10

a1 = 20

d = 5

S10 = 10/2 (2(20) + (10 - 1)5) =  425

A student records the total number of minutes spent reviewing lessons over several days:

105, 106, 109, 114, 121

How many total minutes will be recorded on the next day?

Answer: 130 minutes

Explanation & Solution:

Find the differences:

106 − 105 = 1

109 − 106 = 3

114 − 109 = 5

121 − 114 = 7

The differences are consecutive odd numbers.

Next difference = 9 and 121 + 9 = 130

A student arranges chairs in square formations for an event.

The number of chairs used is:

121, 144, ___, 196, 225

How many chairs were used in the missing arrangement?

Answer: 169 chairs

Explanation & Solution:

These numbers are perfect squares: 112 = 121, 122 = 144, 132 = 169, 142 = 196, 152 = 225

400

What will be the sum of the first 100 positive integers?

Answer: 5050

Explanation & Solution:

Arithmetic series:

A student tracks the total number of target steps that he needs to accomplish provided by a fitness app at the end of each week:

1,300 steps,  16,900 steps, 219, 700 steps, ...

What pattern rule is used by the app to generate this sequence?

Answer:

Multiply by 13 each time.

Explanation:

Check the ratio between consecutive terms:

16,900/1300 = 13

219,700/16,900 = 13

Since each term is obtained by multiplying the previous term by the same constant (13), the sequence follows a geometric pattern with a common ratio of 13.

A school auditorium increases the number of seats per row following this pattern:

120, 124, 130, 138

How many seats will be in the next row?

Answer: 148 seats

Find the differences:

+4, +6, +8

The increase goes up by 2 each time.

Next increase = +10 and 138 + 10 = 148

A school records the number of books borrowed per month from the library:

1,245 , 1,305 , ___ , 1,485 , 1,605

What was the number of books borrowed during the missing month?

Answer: 1,385

Explanation & Solution:

Find the differences between known terms:

1,305 − 1,245 = 60

1,485 − 1,385 = 100

1,605 − 1,485 = 120

To keep a consistent increasing pattern, the differences increase by 20: +60, +80, +100, +120,

So the missing term is: 1305 + 80 = 1385

A student saves ₱120 in the first week and increases savings by ₱15 each week.

How much money will the student save in total after 20 weeks?

Answer: ₱5,250

Explanation & Solution:

Use the sum of an arithmetic series: Sn = n/2 (2a1 + (n - 1)d)

Where:

n = 20

a1 = 120

d = 15

S20 = 20/2 (2(120) + (20 - 1)15) =  5250
