According to the information the sequence is Arithmetic Progression. Let us assume that ๐1 = ๐
๐ 2 = ๐ + ๐
๐3 = ๐ + 2๐ and so on where Mn = ๐ + (๐ โ 1)๐
So, the terms are:
๐, ๐ + ๐ , ๐ + 2๐, ๐ + 3๐, ๐ + 4๐, ๐ + 5๐, ๐ + 6๐
Now, we can see that the sum of
Now, ๐2 + ๐4 + ๐6 = ๐ + ๐, ๐ + 3๐, ๐ + 5๐,
48 = 3๐ + 9๐ โ 16 = ๐ + 3๐
Therefore,
๐1 + ๐3 + ๐5 + ๐7 = ๐ , ๐ + 2๐, ๐ + 4๐, ๐ + 6d
= 4๐ + 12๐
= 4(๐ + 3๐)
= 4 ร 16
= 64
