What will be the value Burger + FrenchFries x ColdDrink ?
Check your answer:-
From the first equation we can say that ColdDrink = 10
than from the second Burger = (20 – 10)/2 = 5
and from the third equation FrenchFries= (9 – 5)/4 = 1
Thus Burger + FrenchFries * ColdDrink = 5 + 1*10 = 15
here as per BODMAS 5 + 1*10 will be 5 + 10 = 15
What will be the next number in this series?

16, 91, 256
2^4, 3^4, 4^4
next difference should be 5^4 i.s. 625, thus the next number should be 354+625 => 979
-1¹²¹ -1¹²² -1¹²³ -1¹²^⁴ =?

-1¹²¹-1¹²² -1¹²³-1¹²^⁴ = -1-1-1-1 = -4
What will be the next number in this series?
11,15,19,18,26,21,32, 24,37,____
Check your answer:-
Next number
first series is AP with a decreasing difference
11 -> 19 => 8
19 -> 26 => 7
26 -> 32 => 6
32 -> 37 => 5
thus next number should be 37 + 4 => 41
second series is AP with a difference of 3
15, 18, 21, 24 => next number should be 27
If 1*36=36
8*23=23
8*67=1
Then
9*10=?
2, 7, 4, 5 => 100
4, 9, 8, 7 => 400
2, 7, 3, 6 => ?
0, 1, 5, 19, 65, 211, ?
Check your answer:-
thus
3^0 – 2^0 = 1 – 1 = 0
3^1 – 2^1 = 3 – 2 = 1
3^2 – 2^2 = 9 – 4 = 5
3^3 – 2^3 = 27 – 8 = 19
3^4 – 2^4 = 65
3^5 – 2^5 = 211
3^6 – 2^6 = 729 – 64 = 665
There is one more way to solve this
3*previous number + 2^(n-1)
0x3+1=1;
1×3+2=5;
5×3+4=19;
19×3+8=65;
65×3+16=211;
211×3+32=665;
wondering how it is possible?
lets solve 3*previous number + 2^(n-1)
=> 3*(3^(n-1) – 2^(n-1)) + 2^(n-1)
=> 3^n – (2+1)*2^(n-1) + 2^(n-1)
=> 3^n – 2^n – 2^(n-1) + 2^(n-1)
=> 3^n – 2^n i.e. our first equation
