ANSWER: 9460
Step-by-step explanation:
ARITHMETIC PROGRESSION: a, a+1d, a+2d, a+3d,
IT IS MENTIONED 25 CONSECUTIVE NUMBERS. HENCE d=1
Now,
SUM OF 25 CONSECUTIVE NUMBER ACCORDING TO AP = n/2(a+a+24d)
= 25/2(2a+24) [d=1]
Therefore,
(25/2(2a+24))/25=98
=> a+12=98
=> first number i.e. a = 86
=> last i.e. 25th number = 86+24=110
