The sum of the reciprocals of 2 consecutive integers is 32/132
lisabon 2012 [21]
SOLUTION:

x + x + 1 = 132 / 32

2x + 1 = 33 / 8

2x = 33 / 8 - 1

2x = 25 / 8

x = 25 / 8 / 2

x = 25 / 16

The first number is 25 / 16. Therefore, as the second number is consecutive we simply add 1 to the first number to achieve the second number as displayed below:

Second number:

= x + 1

= 25 / 16 + 1

= 36 / 16

= 9 / 4

ANSWER:

Therefore, the first number is 25 / 16 and the second number is 9 / 4.

Hope this helps! :)

In the arithmetic sequence {13, 6,-1,-8,...}, what is the common difference?
pav-90 [236]

════════ ∘◦❁◦∘ ════════

<h3>Answer = -7</h3>

════════════════════

<h3>Known</h3>

a = 13

U2 = 6

U3 = -1

U4 = -8

════════════════════

<h3>Question</h3>

d = ..?

════════════════════

<h3>Way to do </h3>

#since it gives a lot of number, i will just pick one of the nth term, ill choose U2

Un = a + (n-1)d

U2 = 13 + (2-1)d

6 = 13 + d

6 - 13 = d

d = -7

════════════════════

<h3>Note</h3>

• The formula of arithmetic sequence

<h2>Un = a + (n-1)d</h2>

n = nth term

a = first term

d = common difference
