The correct option is
D cannot be determined
Sum of first ten 10 consecutive natural numbers is 45 (p=10)
Also, the sum of 14+15+16 = 45 [
453= (15)] (p=3)
Sum of 22+23 = 45 [
452=22.5] (p=2)
Sum of 5, 6, 7, 8, 9, 10 = 45 [
456=7.5] (p=6)
Thus, using both statements also, the answer cannot be determined.
Alternate Method:
p2(2a+p−1)=45 Now, possible values of p are 1, 2, 3, 5, 6, 9, 10, 15, 18, 30, 45, 90.
Out of these, two values of p can be considered - 2 and 6.
Thus, the answer cannot be determined.
