Answer : Difference between the consecutive Numbers are 1^2, 2^2, 3^2, 4^2, 5^2
i.e Required Number= 32+25=57 - 1
Answer : Difference between the consecutive No’s are 5, 15, 25, 35, 45
So, Required Number =88+45=133 - 2
Answer : Difference between the consecutive Numbers are 9, 13, 17, 21, 25
So, Required Number=66+25=91 - 5
Answer : Difference between the consecutive Numbers are 99, 88, 77, 66, 55
So, Required Number=139 – 44 = 95 - 4
Answer : Difference between the consecutive Number’s are 8, 16, 32, 64, 128
So, Required Number=133+128=261
