What is the next number in the sequence 7, 2, 0, 7, 8, 4, 3?

Answer = 11

Since,

The difference between a term and the fourth term from its position is decreasing by 1.

i.e.,

Sequence => 7 , 2 , 0 , 7 , 8 , 4 , 3 , ?

For Terms,

1st and 5th = 7 - 8 = -1

2nd and 6th = 2 - 4 = -2

3rd and 7th = 0 - 3 = -3

4th and 8th = 7 - ? = -4 (By observation)

Therefore,

Missing no. (?) = 7 - (-4)

? = 11
