a1 = a

a5= a+(n-1)d = a +4d

a10 = a +9d

a15= a+14d

a20 = a+19d

a24 = a+23d

now, adding all,

a1+a5+a10+a15+a20+a24 = 225

⇒a + a+4d +a+9d+ a+14d +a+19d +a+23d = 225

⇒6a + 69d = 225

⇒3(2a+23d)= 225

⇒2a +23d = 75______(1)

now,A/q

a1+a2+a3........a24 = (n/2)[2a +(n-1)d]

here, n = 24

(24/2)[2a +(24-1)d]

=12[2a +23d]

from equation (1)

2a +23d = 75
