Question

84,64,46,30,? then what will be the value of question mark​

Answer 1

16 answer...

DESCRIBED:

84-20=64

64-18=46

46-16=30

30-14=16

Answer 2

Given $84, 64, 46, 30, .....$

We need to find the fifth term of this sequence

Differentiate the second term and the first term of the sequence

$=64-84\\=-20$

Differentiate the third term and the second term of the sequence

$=46-64\\=-18\\=-20+2$

Differentiate the fourth term and the third term of the sequence

$=30-46\\=-16\\=-18+2$

Continuing this process, it is clear that in every difference 2 will increase.

Therefore the fifth term is

$=30-16+2\\=14+2\\=16$

Hence, the fifth term of the sequence is 16.
