The 2th term of The A.P is 7 and 9th term is 28, Find The comon difference and The first term.
1 answer:
Answer:
difference = 3, first term = 4
Step-by-step explanation:
given, a2 = 7
a9 = 28
wkt, a2 = a + d = 7
<u>a9 = a + 8d</u><u> </u><u>=</u><u> </u><u>28</u>
- 7d = - 21
therefore d = 3
and wkt, d = a2 - a
a = 7 - 3 = 4

10,000 = 5,000(1+0.15)^x
2 = (1.15)^x
logbase(1.15) of 2 = x
x = ~4.96
Subtract 5 from both sides
X^2 +8x =-5
2. 8/2=4
3. 4^2=16
Add 16 to both sides
X^2+8x+16=-5+16
Is 2/7 four time
so is 2•4/7=8/7 =1 1/7
