Answer:
Terms are 2 , 3 , 7 , 31
Step-by-step explanation:
1) given a1 = 2
an+2 = 2(an) -1
put n = 1
a1 + 2 = 2a1 -1
put value of a1 in above
you'll get a3 = 2² -1
a3 = 4-1
a3 = 3
put n = 3
a3 + 2 = 2a3 -1
a5 = 2³-1
a5 = 8-1
a5 = 7
put n = 5
a5 + 2 = 2a5 -1
a7 = 2⁵ -1
a7 = 32 -1
a7 = 31
Hope you got it.
Similarly you can find 2nd one's term t23
tn = 5*n -4
here n = 23
t23 = 5 * 23 - 4
t23 = 115 -4
t23 = 111
Hope this helps you.

Umm this is math not French or whatever is the language
The "th" family is a little confusing but you look and find the millionth place. It's basically backwards.
0 is tenths
6 is hundredths
7 is thousandths
3 is ten-thousandths
5 is hundred-thousands
9 is millionths
the number next to it is a 9 (rule round up if it's greater than 5)
since the number is a 9 you have to round up even one more making the 5 a 6
