i want to calculate the frequency

Define frequency.

This formula will return the count of 1's in the range A2, A26, A50, A74:

=SUMPRODUCT(--(MOD(ROW(A2:A74),24)=2),--(A2:A74=1))

Or, this version will account for new row insertions above the range:

=SUMPRODUCT(--(MOD(ROW(A2:A74)-ROW(A2),24)=0),--(A2:A74=1))
