Answer:
443
Step-by-step explanation:
7 , 14 , 49 , 88 , 205 , 324 , ?
take difference of each term
7 , 35 , 39 , 117 , 119 , ?
Here,
first term=7
second term=7*5=35
third term=35+2=39
fourth term=39*5-2=117
fifth term=117+2=119
so,sixth term should be 119*3-2=119(this is because the first and third terms are being multiplied with reducing number of 2 from 5 in alternative series to get the second and fourth terms , as fifth term is in the series it should be multiplied by 1 according to the series to get the sixth term)
Now as these are the differences of the original series we mus add 119 to the sixth term in the original series to get the seventh one which is 324+119=443
