Answer:
129
Step-by-step explanation:
Average of first two no. s = 201.5
sum of first two no.s /2 = 201.5
sum of first two no.s =201.5 x 2 = 403
similarly,
Average of last ywo no.s = 196
sum of last two no.s =196 x 2 = 392
Let the third no. be a .
We know,
sum of all the no.s = 924
403 + 392 + a =924
795 +a = 924
a = 924-795 = 129 . ans. ❤️
