Interesting series!first three numbers in each term are pretty simple. they are consecutive numbersthe last number is the product of second and third numberex.4*3=124*5=206*7=427*8=56the second last number is the last number plus the square of first numberex.12+2^2=1620+3^2=2942+5^2=6756+6^2=92hence following the same pattern30+4^2=XX=46 Thanks & Regards Saurabh Singh, askIITians Faculty B.Tech.
