Part A:
1) 16
2) -25
3) 9
4) -7
I'm too lazy to do the rest, just pay attention in class next time
First term a1 = 6+5 = 11
second term = 12+5 = 17
common difference = 6
Sum of n terms:-
Sn = (n/2) [ 2a1 + d(n - 1)]
Sum of 30 terms:-
S30 = (30/2)[ 2*11 + 6(30-1)]
= 15 * ( 22 + 174)
= 15 * 196
= 2940 Answer
<span>Multiple: 9 * <span>8/9</span> = (<span>9*8/1*9) </span>= <span>72/9</span> = 8/1 = 8
Multiply both numerators and denominators. Result fraction keep to lowest possible denominator <span>GCD(72, 9) = 9</span></span>
