Which term of the arithmetic progression 88, 90, 92,
94... is 142?Solution
Given; 88, 90, 92, 94... T = 142 a=88 d=2 Tn=a+(n-1)-d 142=88+(n-1)-2 54=2n-2 56 = 2n n=28 Hence that post is the 28th.
5466.97 - 3245.01 + 1122.99 = ? + 2309.99
35.11% of 159.99 + √195.97 ÷ 7.02 = ?
20.22 × 11.99 + 140.15 = ?
999.99 + 99.99 + 99= ?
16.99% of 399.99 ÷ 17.17 = ? ÷ 15.15
