Answer:
The value of T₂₀ - T₁₅ is <u>-20</u>.
Step-by-step explanation:
<u>Given</u> :
<u>To</u><u> </u><u>Find</u> :
<u>Using Formula</u> :
General term of an A.P.
- >> Tₙ = nᵗʰ term
- >> a = first term
- >> n = no. of terms
- >> d = common difference
<u>Solution</u> :
Firstly finding the A.P of T₂₀ by substituting the values in the formula :
Hence, the value of T₂₀ is a + 19d.
Secondly, finding the A.P of T₁₅ by substituting the values in the formula :
Hence, the value of T₁₅ is a + 14d
Now, finding the difference between T₂₀ - T₁₅ :
Hence, the value of T₂₀ - T₁₅ is -20.
Answer: 2.5 gallons
Step-by-step explanation:
Given that:
Gallons of paint had = 6.25 gallons
Amount needed to paint room = 2/5 of the paint
Gallons of paint needed :
