The Mean of first three term is 14 and the mean of next two terms is 1...
Solution:
Given: Mean of first three terms = 14
Mean of next two terms = 18
Let the first three terms be a, b, c.
Let the next two terms be d and e.
Finding the Sum of first three terms:
Mean of first three terms = (a + b + c) / 3 = 14
Therefore, a + b + c = 42
Finding the Sum of next two terms:
Mean of next two terms = (d + e) / 2 = 18
Therefore, d + e = 36
Finding the Mean of all five terms:
Mean of all five terms = (a + b + c + d + e) / 5
Substituting the values of a+b+c and d+e, we get:
Mean of all five terms = (42 + 36) / 5
Mean of all five terms = 78 / 5
Mean of all five terms = 15.6
Therefore, the mean of all five terms is 15.6.

Let x1,x2,x3 be the first three terms
Mean =(x1+x2+x3)/3
⇒14=(x1+x2+x3)/3
⇒x1+x2+x3=42
Let x4,x5 be the next 2 terms
Mean=(x4+x5)/2
18=(x4+x5)/2
⇒x4+x5=36
Required mean= (42+36)/5 = 15.6
Mean =(x1+x2+x3)/3
⇒14=(x1+x2+x3)/3
⇒x1+x2+x3=42
Let x4,x5 be the next 2 terms
Mean=(x4+x5)/2
18=(x4+x5)/2
⇒x4+x5=36
Required mean= (42+36)/5 = 15.6
