Question

if....1=5 , 2=10, 3=30, then 4=?

Answer 1

Your answer will be 4=120 because if you see how the pattern is going you'll notice that they are multiplying the last number to the first number. For example:
1=5, 2=10, 3=30

5 10
x 2 x 3
___ ___
10 30
So that means that:
30
x 4
___
120

Answer 2

The fourth term of the sequence will be 110

The given expression forms a sequence 5, 10, 30 ...

First term = 5

Second term = 10

Third term = 30

Let the fourth term be x

Taking their common difference

10 - 5 = 5

30 - 10  = 20

Since the multiplicity of the common difference is 4

Then T4 = 20(4) + 330

T4 = 80 + 30

T4 = 110

Hence the fourth term of the sequence will be 110
