Questions on Number Series Quiz-1

Here, there are two alternating patterns, one addition and one subtraction. The first starts with 2 and increases by 2; the second starts with 44 and decreases by 3.

There are three parallel series going on in this question. The 1st, 4th, 7th terms are using logic of -1, 2nd, 5th and 8th terms are using logic of +1 and 3rd, 6th and 9th terms are using logic of +1 again. Answer will be 4, which belongs to 1st, 4th and 7th term.

There are two series:
Ist : 17 14 11 8 and 2nd: 16 12 8 ?
In first series, -3 , -3 ,-3….. and in 2nd series , -4 , -4 ,-4….
Therefore, next term will be 8 – 4 = 4.

The given series is a prime number series. Hence the next prime number in this sequence would be 41.

The sequence is a combination of following two series:
I. 3, 8, 13, 18, 23 and II. 12, 19, 32, 42, 52
The pattern in I has a constant difference of +5, and the pattern in II has a constant difference of +10. So, in II, 19 is wrong and should be replaced by (12+10) i.e. 22

The sequence is a combination of two given series:
I. 31, 41, 52, 61, 71 and II. 2, 3, 4, 5, 6
So, the pattern in I is + 10
Thus, 52 is wrong and should be replaced by (41 + 10) i.e. 51.

The sequence is a combination of the following two series:
I. 10, 19, 39, 73, and II. 5, 12, 26, 54
The pattern in I becomes + 9, + 18, + 36, So 39 should be replaced by 37. So, 39 is wrong.

The given sequence is a combination of two series:
I. 1, 9, 25, 49 and II. 10, 16, 26
The pattern in I is +8, +16, +24.
The sequence in II is 32 + 1, 42 + 1, 52 + 1
So, 16 is wrong and must be replaced by (42 + 1) i.e. 17.

1 = 13 , 125 = 53, 729 = 93. So, next number would be 133= 2197
Therefore, 2177 is wrong.
