Answer:
a15 = 35
Step-by-step explanation:
Given:
a3 = 11
a6 = 17
Find:
a15 = ?
Computation:
a3 = 11 ⇒ a+ 2d = 11..........Eq1
a6 = 17 ⇒ a + 5d = 17...............Eq2
From Eq2 - Eq1
⇒ 3d = 6
⇒ d = 2
And a = 7
So,
⇒ a15 = a + 14d
⇒ a15 = 7 + 14 (2)
⇒ a15 = 7 + 28
⇒ a15 = 35
To start off, you have to change 2/3 into 3/2 and then multiply it by 3/4. (Which the equation becomes into 3/4 × 3/2.) Then solve 3/4 × 3/2 =9/8 or 1 and 1/8.
