Question

2 ,12 ,36 ,80 ,150 ,?

Answer 1

Ans. Series is 2, 12, 36, 80, 150, ?

Step -I Difference b/w steps of given series -

10, 24, 44, 70, X (let diff b/w 150 & ? is X)

Step -II Difference b/w series of steps I-

14, 20, 26, Y (let diff b/w 70 & X is Y)

Step III Difference b/w series of Step II-

6, 6, 6 ( Here 6 is common diff b/w all steps)

Now,

Step II will be - 14, 20, 26, 32 ( Because Y = 26+6)

Step I will be- 10, 24, 44, 70, 102 ( Because X = 70+32)

therefore given series will be-

2, 12, 36, 80, 150, 252 ( Because ? = 150+102)

So answer is 252.
