Answer is : 24
As the series is formed
1^2-1 = 0
2^2+1 = 5
3^2-1 = 8,
4^2+1 = 17
5^2-1 = 24 |
Next number is 216.
This is how series is formed:
1 ^ 2 = 1
2 ^ 3 = 8
3 ^ 2 = 9
4 ^ 3 = 64
5 ^ 2 = 25
6 ^ 3 = 216 |
Next number is : 27.
3,5 number is formed by dividing 2,4 number /2 respectively.
12 is formed = 24/2
18 is formed = 36/2
27 is formed = 54/2 |

Answer is 65.
2+3=5; 5+5=10; 10+7=17; 17+9=26; 26+11=37; 37+13=50; 50+15=65; |
Answer: 0
Explanation:
105-20=85; 85-25=60; 60-30=30; 30-35=-5; -5-40=-45; -45-45=-90; |

ANSWER:
FORMULA SUBSTITUTION:
NUMERATOR: (A+B)^2 -(A-B)^2 = 4AB
DENOMINATOR:AB
=> 4AB/AB=4
THE ANSWER IS 4 |
short cut:
1st portion:untit digit=>
5^2350 only considered power number:(2350-1)/4=remainder 1
5^1+remainder=5^1+1=5^2=25
so unit digit =>5
2nd portion :unit digit=>
7^350 only considered power number:(350-1)/4=remainder 1
7^1+remainder=7^1+17^2=49
so unit digit=>9
Answer=1st portion unit digit+2nd portion Unit Digit
==> 5+9=14
Answer is 4
(Important:(Any Power number-1)/4) |
