- WRONG QUESTION!!
CORRECT QUESTION: Sum of the consequent 7 integers equals 1617. Find the no. of prime numbers in that sequence.
SOLUTION:
Let the numbers be x, x+1, x+2, x+3, x+4, x+5, x+6
Since their sum equals 1617, we have-
x+(x+1)+(x+2)+(x+3)+(x+4)+(x+5)+(x+6)=1617
7x+21=1617
7x=1596
x=228
Hence the numbers are: 228,229,230,231,234,235,236
