Hello Aspirant,

See 354 will be written after the given series to continue it and let me make more easier to get an understanding of the series, so in the series if you observe than it the first number which is 13 when multiplied by 2 and then from the result 2 is subtracted and the final result will be the next number.

Pattern is :-

24 = (13*2) - 2

46 = (24*2) - 2

90 = (46*2) - 2

178 = (90*2) - 2

354 = (176*2) - 2

And it keeps going in similar pattern.

I hope this information helps you.

Good Luck!!
