Answer:
7+<u>21</u>+15+19+.....+79
Here 21 be replaced by <u>11</u>.
Now., common diffrence btw terms , d = 11-7 = 4
first term , a = 7
Last term , l = 79
number of terms = ( a + l ) ÷ d
=( 7 + 79 ) ÷ 4 = 86 ÷ 4 = 21.5 { It cannot be in decimal }
<u>There's some mistake in the terms you provided please check your question again...</u>
Answer:
20
Step-by-step explanation:
1/2(a+b)=180
1/2(6+12)=18
1/2(18)=180
9/9=180/9
=20
It's wrong because 6x10 to the 3rd power is 6000, not 180.
