<h3>Given AP </h3>
<h3>To find</h3>
<h3>Solution</h3>
- a₁₂ = a + 11d = 62
- a₂₀ = a + 19d = 102
<u>Subtract the first equation from the second one:</u>
<u>Find a:</u>
- a + 11*5 = 62
- a = 62 - 55
- a = 7
<u>Find the sum of the first 20 terms:</u>
- S₂₀ = 1/2*20(a + a₂₀) = 10(7 + 102) = 10(109)= 1090
