Question

(10,20,30,18,? ) missing series pattern????​

Answer 1

If the magnitude of vectors A, B and C are 5, 4 and 3 units respectively and A=B+C, what is ... If vector A.B=0 & vector [ A×B] =0, then what will be the angle between vector B & C?

Answer 2

The given series are:

10, 20, 30, 18, ?

We have to find, the value of missing pattern (?) is:

Solution:

The given series has two series.

The first series(Odd place):

10, 30, ?

The pattern follow:

Previous number + 20, Previous number + 20, .....

30 = 10 + 20 = 30

? = 30 + 20 = 50

The secondt series(Even place):

20, 18, ?

The pattern follow:

Previous number - 2, Previous number - 2, .....

18 = 20 - 2 = 18

? = 18 - 2 = 16

∴ Missing series (?) = 50 and 16
